I simplified it, but in fact it is not only 'a' to be eliminated, but
thousands of rows.
Can I use:
col1sample<-sample(col1,2,replace=T)
selection <- subset(somedf, col1= col1sample) # why do we say here
somedf, cant we just restrict our condition to one row only?
I was also thinking of doing something like:
col1sample<-sample(col1,2,replace=T)
col2selection<-col2[col1==col1sample]
col2sample<-sample(col2selection,2,replace=T)
Does it make sense?
