Man, the original reply told you to use backticks `` rather than
double quotes "". They are very different in R; see ?Quotes
And GSE19829-GPL570_eset is really a bad name. I recommend you to
rename it.

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
If you use Yihui's advice, you should only back-tick around the
dataframe name and not around the column name.
The error is that R atomic vector operator invalid.
Because you are trying to divide a character value by a number.

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

Hey,
I keep getting the following warning:

Hi Ben --
'-' is being parsed as a minus sign; you could (I think) quote it
`GSE19829-GPL570_eset`
or better come up with a legal name.

Error in summary(GSE19829 - GPL570_eset$vital_status) :

This error does not happen on other of my other .Rd files. None
of the
other .Rd files have a "-" character in their title. for
example, the
other files have the following:
data(GSE1234)
OR
data(GSE5678)
I think the issue is the "-" character, but I'm not sure. Does
anyone
know
if this is the case? And if so, how do I fix it? If not, any
other
suggestions?
Much thanks!
