Two choices (and in any case, don't call your input dataframe just  
"file", although that is probably not why you are having problems):

option 1) Type in:

file_inp <-read.table("",header=T,skip=24)
### then click-hold-drag the file from a Finder window to the R  
console until the cursor bar is between the two quotes, then "release- 
click".

optiuon 2)

file_inp<-read.table(file=file.choose(),header=T,skip=24)

## and then navigate to the location of your file using the Mac File  
Chooser window.

And in the future, such questions should go to the Mac-SIG list.
