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 package
Here's another approach using the plyr package:
# Function to process each row of input:
g - function(d) {
y - unlist(d$observations)
if(length(y) 0)
data.frame(site = d$site, sector = d$sector, y = y) else NULL
}
library('plyr')
ddply(input, .(site), g)
site sector y
