How to write R code similar to SAS PROC SUMMARY or SPSS Data Audit ? Is there any such R package available which can do automatic data manipulations (like removing variables/columns which have more than 90% constant values, providing summary of each variable, etc etc).

  1. Just use summary() ot lists NAs seperately
  2. Use na.rm=TRUE as an option if you want NAs to be ignored ( as in mean(objectname, na.rm=T)
  3. I have not used this package but they may help

Hope this helps @whystatistics
