[BioC] Mising data

[Alex F. Bokov]

Dear Ms. Gu:

The following message appears to be in reference to a problem similar to 
the one you're having.

http://www.mail-archive.com/r-help@stat.math.ethz.ch/msg13521.html

Note that the author of that message seems to be running an older 
version of R. If that's not your problem, then doing the thing he tried 
might work for you-- namely invoking R with the --max-mem-size=1024M 
command-line flag.

Alternatively, you can set the memory limit from inside of R with this 
command: memory.limit(size=1024)

By the way, how much RAM do you have in your computer and how large is 
the swap-file?

>Hi,

I suspect this error message indicates that R is incorrectly parsing the 
number of rows and columns. How many rows and columns does it report 
reading? Do they match what's supposed to be in your data? I don't know 
about this particular package, but when I have this problem reading 
tabular data in general, changing the column names and row names so they 
contain no spaces usually fixes it.

>Also,I tried to read one file at a time, I got the following messages,

>1: number of items read is not a multiple of the number of columns 
>2: NAs introduced by coercion 
>3: NAs introduced by coercion 
>4: NAs introduced by coercion
