Dear reader,
I have the following problem:
I have some string with numbers like k. I want
to have a table like the function table() gives. However I am not able
to call the first row, the 1, 2, 3, 5, 6 or 9. I tried to do that by a
data.frame, but that doesn't seem to work either. The
k-c(1,1,1,1,1,3,5,6,2,1,3,9,2,3,1,1,1)
table(k)
k
1 2 3 5 6 9
9 2 3 1 1 1
names(table(k))
[1] 1 2 3 5 6 9
as.numeric(names(table(k)))
[1] 1 2 3 5 6 9
x - table(k)
as.numeric(names(table(k)))[4]
[1] 5
You can always save the (numeric version of the) names as an object, too.
Does that help?
