Dear list,

I need to read a big txt file (around 130Mb; 23800 rows and 49 columns)
for downstream clustering analysis.

I first used "Tumor <- read.table("Tumor.txt",header = TRUE,sep = "\t")"
but it took a long time and failed. However, it had no problem if I just put
data of 3 columns.

Is there any way which can load this big file?

Thanks for any suggestions!

Sincerely,
     Alex
