Hi Martin,

Thanks! You were right.  Quotes seemed to work, except I kept running into
a problem on the following line:

time <- "GSE19829-GPL570_eset$days_to_death" / 365

The error is that R atomic vector operator invalid.  It's actually much
easier if I could use quotes rather than re-name-- so is there any way to
put quotes around the columns in "GSE19829-GPL570_eset" such that it does
what i want it to?

In the above "time" example, I just want to take the values in the column
and divide by 365, but the quotes are messing it up. Any clarification
would be really greatly appreciated!

Thanks!

Ben
