Subject: Re: [R] R for loop stops after 4 iterations
There's a seeming inconsistency in this question -- namely, you provide an
example of a data frame with 4 columns but say it is 27x3
-- but I think your question comes from a misunderstanding of what
length(e) calculates.
Hi:
Here are a couple of ways, using the data snippet you provided as the
input data frame e.
Start by defining the function, which outputs a percentage:
f <- function(n, mean, sd) {
s <- rnorm(n, mean = mean, s = sd)
round(100 * sum(s > 0.42)/length(s), 4)
}
(1) Use the plyr packag

Oops!!
Meant pnorm(, lower.tail = FALSE) -- don't do qnorm or bad things will happen.
Sorry,

There's a seeming inconsistency in this question -- namely, you
provide an example of a data frame with 4 columns but say it is 27x3
-- but I think your question comes from a misunderstanding of what
length(e) calculates. For a data frame it gives the number of columns
back. Hence if you have a 27
