analysis of variance test
Dear Nezahat In future it would be helpful if you 1 - gave us the data so we can reproduce what you are doing 2 - told us what the error was in case we cannot replicate ti 3 - did not post in HTML as it messes up everything in your post What did you think x1 <- numeric was going to do? Try x1 <- numeric str(x1)

Let's say I have 12 observation of 5 variables and my first variable is categorical (with 4 different levels). I am trying to find out statistical significance difference between these categorical levels for each variable, but my function is not working! Please note that my data "x" are in data.frame format.
Any suggestion would be helpful.Many thanks.
function(x)
{
x1 <- numeric
x2 <- numeric
for(i in 2:length(x)) {
x1[i] <- summary(aov(x[, i] ~ factor(x[, 1])))
x2[i] <- x1[i]$Pr[1] #Pr is the probability values
if(x2[i] < 0.06)
x2[i] <- 1
else x2[i] <- 0
}
x2
}
