Using expss package I am creating cross tabs by reading SPSS files in R. This actually works perfectly but the process takes lots of time to load. I have a folder which contains various SPSS files(usually 3 files only) and through R script I am fetching the last modified file among the three.
setwd('/file/path/for/this/file/SPSS')
library(expss)
expss_output_viewer()
#get all .sav files
all_sav <- list.files(pattern ='\\.sav$')
#use file.info to get the index of the file most recently modified
pass<-all_sav[with(file.info(all_sav), which.max(mtime))]
mydata = read_spss(pass,reencode = TRUE) # read SPSS file mydata
w <- data.frame(mydata)
args <- commandArgs(TRUE)
Everything is perfect and works absolutely fine but it generally takes too much time to load large files(112MB,48MB for e.g) which isn't good.
Is there a way I can make it more time-efficient and takes less time to create the table. The dropdowns are created using PHP.
I have searched for this and found another library called 'haven' but I am not sure whether that can give me significance as well. Can anyone help me with this? I would really appreciate that. Thanks in advance.
