Find row number from a row name in R

Question

How can I find the row number of a particular row name in R? I have found functions which allow you to find a row number for a particular matrix value, but not from a row name.

Answer 1

You can use which

which(rownames(dat) == "theName") 

Geode

Ok thanks. I did this, but this is what R returned: integer(0) It should be returning a row # somewhere in the 500s. Any ideas on what I may be doing wrong? – Hearten

@JoelleMarie the name is probably wrong, eg which(c("a","b") == "c") returns integer(0) – Geode

@Hearten in my case the labels of my dataset happened to have a lot of spaces after the name, so i had to include those spaces as part of the label I wanted to find to get it working. By typing row.names(dat) you should see if this was also your case, provided this is still of interest for you. – Cuevas
