Hi,
the R code:
a <- matrix(c(1,5,4,3,7,10,34,4,3,8,6,5,12,17,45,3,2,45,46,47,3,4,22,12,21),
nrow=5)
rownames(a) <- c("a","b","c","d","e")
a
a[which(a[,3] < 8), ]
a[which(a[,3] < 6), ]
produces the following output:
> a
[,1] [,2] [,3] [,4] [,5]
a 1 10 6 3 3
b 5 34 5 2 4
c 4 4 12 45 22
d 3 3 17 46 12
e 7 8 45 47 21
> a[which(a[,3] < 8), ]
[,1] [,2] [,3] [,4] [,5]
a 1 10 6 3 3
b 5 34 5 2 4
> a[which(a[,3] < 6), ]
[1] 5 34 5 2 4
I actually thought it must be rather easy to somehow extract the row name
when the result is just a vector as in the second example and not a matrix.
I tried several ways but without any success.
Any advice?
Best,
syrvn
