[R] exclude data for boxplot stats using mathematical operator

[e-letter]

Readers,

I have a data set as follows:

1,1
2,2
3,3
4,4
5,3
6,2
7,-10
8,-9
9,-3
10,2
11,3
12,4
13,5
14,4
15,3
16,2
17,1

I entered this data set using the command 'read.csv'. I want to
exclude values fewer than zero in column 2 so then I tried the
following command:

boxplot.stats(x[>0,2],do.conf=FALSE)
Error: syntax error, unexpected GT, expecting ',' in "boxplot.stats(x[>"

Any help please?

Yours,
