# ----------------------------------------------------------------------------- # R programming statements for h218 data # # This file contains programming statements needed to import the ASCII data # file (.dat) into R. The R programming language has the capability to produce # appropriate standard errors for estimates from a survey with a complex sample # design such as the Medical Expenditure Panel Survey (MEPS). # # The input file is the ASCII data file (h218.dat) supplied in this PUF # release, which can be extracted from the .zip file supplied at the MEPS # website: https://meps.ahrq.gov/mepsweb/data_stats/download_data_files.jsp # # This code imports the MEPS data into R as a data frame called 'h218'. # # Note that additional packages are needed to successfully run this code. To # install these packages, run the 'install.packages' function (shown below). # Once installed, the packages can be called using the 'library' function. # Packages only need to be installed once, but they must be called using the # 'library' function every time a new R session is started. # # Two options are available to run this code: # # 1. Copy and paste the code into an interactive R session. # # The user must first download the ASCII (.dat) file from the MEPS website # and save it to a local directory, which must be defined in the # 'meps_path' variable below. In this example, the local directory is # called 'C:/MEPS'. Note that the path structure will differ on Mac and PC. # # # 2. Call this code directly from an interactive R session. # # (a) If the ASCII (.dat) file has already been downloaded from the MEPS # website and saved to a local directory, the following code can be run # (after re-defining the 'meps_path' variable to point to the location # of the h218.dat file.) # # meps_path <- "C:/MEPS/h218.dat" # source("https://meps.ahrq.gov/mepsweb/data_stats/download_data/pufs/h218/h218ru.txt") # head(h218) # view data # # (b) Alternatively, the ASCII (.dat) file can be downloaded directly from # the MEPS website. The following code can be used to download and # import the h218 data into R without having to manually download, # unzip, and store the file on your local computer. # # url <- "https://meps.ahrq.gov/mepsweb/data_files/pufs/h218dat.zip" # download.file(url, temp <- tempfile()) # # meps_path <- unzip(temp, exdir = tempdir()) # source("https://meps.ahrq.gov/mepsweb/data_stats/download_data/pufs/h218/h218ru.txt") # # unlink(temp) # Unlink to delete temporary file # # head(h218) # view data # # ----------------------------------------------------------------------------- # DEFINE 'meps_path' ----------------------------------------------------------- # 'meps_path' should point to the file path of the ASCII file (h218.dat) # Here, the 'exists' function checks whether meps_path is already defined. This # feature is useful if calling this file from an external source. if(!exists("meps_path")) meps_path = "C:/MEPS/h218.dat" # INSTALL PACKAGES ------------------------------------------------------------ # Uncomment and run this portion if packages are not yet installed # # install.packages("readr") # ************************************** # LOAD PACKAGES --------------------------------------------------------------- # Run this for every new R session library(readr) # DATA FILE INFO ------------------------------------------ # Define start and end positions to read fixed-width file pos_start <- c( 1, 15, 28, 31, 41, 48, 51, 52, 53, 55, 57, 61, 63, 67, 68, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 97, 102, 104, 106, 111, 113, 115, 117, 119, 121, 123, 125, 128, 130, 132, 134, 136, 138, 140, 142, 149, 151, 153, 155, 157, 159, 161, 163, 165, 170, 174, 176, 178, 185, 187, 196, 198, 204, 206, 208, 210, 219, 221, 223, 226, 228, 230, 232, 240, 242, 251, 253, 262, 264, 266, 268) pos_end <- c( 14, 27, 30, 40, 47, 50, 51, 52, 54, 56, 60, 62, 66, 67, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 96, 101, 103, 105, 110, 112, 114, 116, 118, 120, 122, 124, 127, 129, 131, 133, 135, 137, 139, 141, 148, 150, 152, 154, 156, 158, 160, 162, 164, 169, 173, 175, 177, 184, 186, 195, 197, 203, 205, 207, 209, 218, 220, 222, 225, 227, 229, 231, 239, 241, 250, 252, 261, 263, 265, 267, 269) var_names <- c( "JOBSIDX", "JOBIDX", "JOBNUM", "DUPERSID", "DUID", "PID", "RN", "OrigRnd", "PANEL", "JSTRTM", "JSTRTY", "JSTOPM", "JSTOPY", "RETIRJOB", "SUBTYPE", "STILLAT", "TYPECHGD", "MAIN_JOB", "DIFFWAGE", "StillWorkFTPT", "WhyChngPTToFT", "WhyChngFTToPT", "STILLWRK", "OFFTAKEI", "NOWTAKEI", "ESTBTHRU", "INSESTB", "HIDISAVW", "RvwTotNumEmp", "WHY_LEFT_M18", "JOBTYPE", "NUMEMPS", "ESTMATE1_M19", "MORELOC", "BUSINC", "PROPRIET", "TYPEEMPL", "YLEFT_M18", "YNOBUSN_M18", "HRSPRWK", "HRS35WK", "TEMPJOB", "SESNLJOB", "SICKPAY", "PAYDRVST", "PAYVACTN", "RETIRPLN", "WKLYAMT", "EMPLINS", "JOBHASHI", "OFFRDINS", "DIFFPLNS", "ANYINS", "INUNION", "PROVDINS", "HHMEMBER_M18", "TOTLEMP_M18", "TotNumEmp", "SALARIED", "HOWPAID", "DAYWAGE", "HRSPRDY", "MAKEAMT", "PERUNIT_M18", "HRLYWAGE", "MORE10", "MORE15", "MOREMINM", "GROSSPAY", "GROSSPER", "SALRYWKS", "HRSALBAS", "EARNTIPS", "EARNBONS", "EARNCOMM", "TIPSAMT", "TIPSUNIT_M18", "BONSAMT", "BONSUNIT", "COMMAMT", "COMMUNIT", "INDCODEX", "OCCCODEX", "ADJR5") var_types <- c( "c", "c", "c", "c", "c", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "c", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n", "n") var_types <- setNames(var_types, var_names) # IMPORT ASCII file ----------------------- h218 <- read_fwf( meps_path, col_positions = fwf_positions( start = pos_start, end = pos_end, col_names = var_names), col_types = var_types) # OPTIONAL: save as .Rdata file for easier loading ---------------------------- # Run this to save a permanent .Rdata file in the local working directory # # save(h218, file ="h218.Rdata") # ----------------------------------------------------------------------------- # NOTES: # # 1.
