Hi all,
I have two basic questions, hope you should help me:
1. How do I save a log file in R with the results? For example, in Stata
it can be done by using "log using c:\...\test.txt"
See ?sink.
2. How do I display the execution time of one function like the one below:
CalculaCorrelacao <- function(construto, n) {
library(polycor)
for (i in 2:n){
for (j in i:n+1){
x1 <- construto[[i]]
x2 <- construto[[j]]
temp1 <- polychor(x1, x2, ML = FALSE,maxcor=.9999)
corr[i-1,j-1] <- temp1
corr[j-1,i-1] <- temp1
}
}
return(corr)
}
See ?system.time.
