I have a data frame like this
xx<-data.frame(cbind(Sample=c('Ctrl_6h','1+0_6h','1+200_6h','1+5k_6h','Ctrl_5K_6h','ConA_6h'),
IFIT1=c(24,25,24.7,24.5,24.2,24.8)))
grep('[[:digit:]]h',xx$Sample)
yy<-xx$Sample
strsplit(yy,"_")
I have to extract the time information separated by '_' in the sample names,
i tried grep and strsplit, it looks that i am not providing some information
correctly. I would appreciate if someone can point me to the correct way.
Thanks
Sharad
