If I understand this correctly you are choosing all the rows from each
of cod and lnc which contain .c (ie any character followed by a C) and
deleting the first column from each of cod and lnc. You then correlate
them so that you get the correlation between corresponding columns of
each. Since you do not tell us how you know which column is which it is
hard to answer the question of how R will know.

Hi All,I have 11 human RNA-seq data (control/treatment),The effect of various
drugs on various cancers,I want to calculate the genes-lncRna correlations for
all tumors considered together for network,I did differential expression
analysis and prepared normalized values (rpkm) of coding and lncoding in two
separate file and import them to R, then transpose them and now I want to
calculate corr by this function:
control.corr=cor(cod[grep(".C",cod$name),-1],lnc[grep(".C",lnc$name),-1],method =
"spearman")
if I understand true,I should write the numbers of columns whose related to
control,then I counted all of control`s column and wrote 23 .now my question
is,how does R understand what column is control and what is treatment?
