Dear Community:
Thank you Michael, I did it as you said. However I still have a little
problem with this staff.
I try my lm's in my df1's variables. Let's say: lm1 <- lm( df1$vi) ~ df1$v1
+ df1$v2)
Then I usally type: plot(lm1, 1:4)
I'd like to see in the plots obtained the name of the rown
I've manged this way:
df2 <- df1[-match(784, row.names(df1)), ]
Isn't there any other way?? How can I retrieve/delete three rows with the
same command line?u...@host.com

You probably mean this:
df1[!(rownames(df1) %in% c("2098","2970","784")), ]
Remember, row names are strings: if you give R an integer, it will
interpret it as a row index.

http://r.789695.n4.nabble.com/file/n4099139/df1.xls df1.xls ), let's call it
df1 (and when I type str(df1) it answers data.frame)
df1 has its own rownames (In the .xls the column "id", not 1,2,3, ...), and

Try A[1,,drop=FALSE] - see help("\[")

when I use A[1,], I lost the rowname for it, like below. How could I keep
it? Is there an easy way instead that I have to modify by mys
