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:

Warning in data(GSE19829 - GPL570_eset) :

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.

if(require(affy)){

+   summary(GSE19829-GPL570_eset$**vital_status)
+  }
Error in summary(GSE19829 - GPL570_eset$vital_status) :
  object 'GSE19829' not found
Execution halted

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!

Ben
