you can try      isfar  lt - get load  c  users isfar Rdata      this will assign the variable in isfar Rdata to isfar   After this assignment  you can use str isfar  or ls isfar  or head isfar  to get a rough look of the isfar

If you have a lot of variables in your Rdata file and don t want them to clutter your global environment  create a new environment and load all of the data to this new environment   load file path  C  Users isfar RData    isfar env  lt - new env        Access individual variables in the RData file using     operator isfar env var name     List all of the variable names in RData  ls isfar env

You can also import the data via the  Import Dataset  tab in RStudio  under  global environment   Use the text data option in the drop down list and select your  RData file from the folder  Once the import is complete  it will display the data in the console  Hope this helps

Look at the help page for load   What load returns is the names of the objects created  so you can look at the contents of isfar to see what objects were created   The fact that nothing else is showing up with ls   would indicate that maybe there was nothing stored in your file   Also note that load will overwrite anything in your global environment that has the same name as something in the file being loaded when used with default behavior   If you mainly want to examine what is in the file  and possibly use something from that file along with other objects in your global environment then it may be better to use the attach function or create a new environment  new env  and load the file into that environment using the envir argument to load

It sounds like the only varaible stored in the  RData file was one named isfar   Are you really sure that you saved the table   The command should have been   save the table  file    isfar RData       There are many ways to examine a variable   Type it s name at the command prompt to see it printed   Then look at str  ls str  summary  View and unclass

I think the problem is that you load isfar data frame but you overwrite it by value returned by load   Try either   load  C  Users isfar RData    head isfar    Or more general way  load  C  Users isfar RData   ex  lt - new env    ls str ex

isfar lt -load  C  Users isfar RData    if is data frame isfar       names isfar      If isfar is a dataframe  this will print out the names of its columns

This may fit better as a comment but I don t have enough reputation  so I put it here  It worth mentioning that the load   function will retain the object name that was originally saved no matter how you name the  Rdata file    Please check the name of the data frame object used in the save   function  If you were using RStudio  you could check the upper right panel  Global Environment-Data  to find the name of the data you load
