How to see data from .RData file?

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 <- new.env())ls.str(ex) 

you can try

isfar <- get(load('c:/users/isfar.Rdata'))

this will assign the variable in isfar.Rdata to isfar . After this assignment, youcan use str(isfar) or ls(isfar) or head(isfar) to get a rough look of the isfar.

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.
