Here's one way:
makeframe = function(x){
b = as.data.frame(as.matrix(table(x$Species,x$Species)))
b = b[!(b$Var1 == b$Var2),-3]
data.frame(Year=x$Year[1],Location=x$Location[1],b)
}
result = lapply(split(x,list(x$Year,x$Location)),makeframe)
result will be a list of data fra
Hey All,
So, I am confused how exactly to use nesting loop functions in R to spit out
data frames. I've managed to create a working function for my data set that
generates a data frame for a given set of Year i and Location j; but how
