[R] reset row numbers when extracting a subset of a table

[Gabor Csardi]

Nina, these are not row NUMBERS, but row NAMES. Numbers are actually 
reset, they always start with 1 and they are continuous. Just try
doing 

T[1,]

on your table. If you want to reset row names, you can do this: 

rownames(T) <- seq(length=nrow(T))

or you can even remove them:

rownames(T) <- NULL

Best,
Gabor
