read.ssd {foreign} | R Documentation |
Generates a SAS program to convert the ssd contents to SAS transport format
and then uses read.xport
to obtain a dataframe.
read.ssd(libname, sectionnames, tmpXport=tempfile(), tmpProgLoc=tempfile(), sascmd="sas")
libname |
character string defining the SAS library (usually a directory reference) |
sectionnames |
character vector giving member names. These are
files in the libname directory. They will usually have a
.ssd0x or .sas7bdat extension, which should be omitted. |
tmpXport |
character string: location where temporary xport format archive should reside – defaults to a randomly named file in the session temporary directory, which will be removed. |
tmpProgLoc |
character string: location where temporary conversion SAS program should reside – defaults to a randomly named file in session temporary directory, which will be removed on successful operation. |
sascmd |
character string giving full path to SAS executable. |
Creates a SAS program and runs it.
A data frame if all goes well, or NULL with warnings and some enduring side effects (log file for auditing)
error handling is primitive
