Greetings to all --

I am having a silly problem that I just can't solve.  Someone has given me
an .RData file will hundreds of data frames.  Each data frame has a column
named ResultValue, currently character when it should be numeric.  I want to
loop through all of the data frames to change the variable to numeric, but I
cannot figure out how to do it. My best guess was along the lines of:

frames = ls()
for (frame in frames){
     assign(frame, get(frame), .GlobalEnv)
     frame[,"ResultValue"] = as.numeric(frame[,"ResultValue"])
     }

It doesn't work.  After the assign() the frame object remains the character
name of the dataframe I am trying to change.  If I do the following, the
TEST object comes out just fine.

frames = ls()
for (frame in frames){
     assign("TEST", get(frame), .GlobalEnv)
     TEST[,"ResultValue"] = as.numeric(TEST[,"ResultValue"])
     }

Seems like it should be simple, but I am misunderstanding something and not
following the logic.  Any insight?

Thanks,

Sarah
