Hi Henrique,
Lot of thanks for your advice which is a little complicate to me. It involves
multiple R commands:
d - data()
ne - new.env()
data(list = grep(\\(, d$results[,'Item'], value = TRUE, invert = TRUE),
envir
= ne)
out - eapply(ne, names)
names(which(lapply(lapply(out, '%in%', c(Run, conc, density)), sum) ==
3))
[1] DNase
DNase
Runconc density
1 1 0.04882812 0.017
2 1 0.04882812 0.018
3 1 0.19531250 0.121
4 1 0.19531250 0.124
...
It works for me.
grep - is simliar to sh command grep, egrep, fgrep, rgrep - print lines
matching a pattern
which - differs from sh command which - locate a command
Wonderful !!!
B.R.

Try this:
d - data()
ne - new.env()
data(list = grep(\\(, d$results[,'Item'], value = TRUE, invert = TRUE), envir
= ne)
out - eapply(ne, names)
names(which(lapply(lapply(out, '%in%', c(Run, conc, density)), sum) == 3))
Hi folks,
I need to search the dataset on data with name on heading;
Run conc density
I look at ??help.search and could not resolve;
help.search(pattern, fields = c(alias, concept, title)
What shall I replace pattern?
I suppose replacing alias, concept, title with Run, conc, density ?
Please help. TIA
B.R.
