readECLS_K2011: Connect to ECLS--K 2011 Data

Description

Opens a connection to an ECLS--K 2011 data file and returns an edsurvey.data.frame with information about the file and data.

Usage

readECLS_K2011(
  path = getwd(),
  filename = "childK5p.dat",
  layoutFilename = "ECLSK2011_K5PUF.sps",
  forceReread = FALSE,
  verbose = TRUE
)

Value

an edsurvey.data.frame for the ECLS--K 2010--11 longitudinal dataset

Arguments

path

a character value to the full directory path(s) to the ECLS--K 2010--11 extracted fixed-with-format (.dat) set of data files

filename

a character value of the name of the fixed-width (.dat) data file in the specified path to be read

layoutFilename

a character value of the filename of either the ASCII (.txt) layout file of the filename within the specified path or a character value of the filename of the SPSS syntax (.sps) layout file of the filename within the specified path

forceReread

a logical value to force rereading of all processed data. The default value of FALSE will speed up the read function by using existing read-in data already processed.

verbose

a logical value that will determine if you want verbose output while the readECLS--K2011 function is running to indicate processing progress. The default value is TRUE.
