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
}
