Maybe it is something else.  Did you change shells?  

Reading from '-' still works for me when needed. Here is a quick throw-away
example using awk to pick file size from a directory listing and letting r
summarize it [1]

edd at ron:~$ ls -l /etc | awk '/^-/ {print $5}' | r -e'print(summary(as.numeric(readLines())))' -
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
      0     272     843    7980    2540  219000 
edd at ron:~$

[1] Not that great an example otherwise...
