I have two numeric vectors each of length 17 and each is named the exact
same way.
so
obsnum ppppp ppppm pppmp . dot dot dot......
temp1 is 1417 52 63 85
obsnum ppppp ppppm pppmp . dot dot dot......
temp2 is 1213 41 50 97
what i want to have is a resultant matrix with 2 rows and 16 columns
where the 16 columns are the 2:17 columns divided by the respective
first element in each vector.
( so 52, 63 and 85 should all get divided by 1417 and 41, 50 and 97
should all be divided by 1213 ).
it doesn't have to retain the column names because i can just assign
them again when i am assigning the rownames.
below is my code :
resultmatrix<-rbind(temp1,temp2)
resultmatrix<-resultmatrix[,2:17]/resultmatrix[,1]
colnames(resultmatrix)<-colnames(temp1)
rownames(resultmatrix)<-c("group1","group2")
I'm pretty sure above will work but it seemed kind of ugly and I
wondering if there is a better way because i am trying to improve in R.
if there isn't, that's fine. thanks.
