View source: R/misc.get.s

Description

spss.get invokes the read.spss function in the foreign package to read an SPSS file, with a default output format of "data.frame". The label function is used to attach labels to individual variables instead of to the data frame as done by read.spss. By default, integer-valued variables are converted to a storage mode of integer unless force.single=FALSE. Date variables are converted to R Date variables. By default, underscores in names are converted to periods.

spss.get(file, lowernames=FALSE, datevars = NULL,
         use.value.labels = TRUE, to.data.frame = TRUE,
         max.value.labels = Inf, force.single=TRUE,
         allow=NULL, charfactor=FALSE, reencode = NA)

Arguments

file

input SPSS save file. May be a file on the WWW, indicated by file starting with 'http://' or 'https://'.

lowernames

to.data.frame

see read.spss; default is TRUE for spss.get

max.value.labels

see read.spss

force.single

set to FALSE to prevent integer-valued variables from being converted from storage mode double to integer

allow
