Re: [R] error message from apply()

Replacing colMeans by mean removed the warning messages. Thanks However, when I precompute thr, and pass it to function(x), the error returns. Using the shorter data2_1, doesn't give any warnings. What is happening ? data2_1 <- matrix(c(0.9584190, 0.2710325, -0.9495618, -0.1301772, -0.7539687, 0.

Re: [R] error message from apply()

The error message was coming from the call to colMeans where 'x' was not a matrix; it was a vector that resulted from the 'apply' call. Did you intend to use 'mean' instead like this example: > data2_1 <- matrix(c(0.9584190, 0.2710325, -0.9495618, -0.1301772, -0.7539687, + 0.5344464, -0.8205933, 0

[R] error message from apply()

Hi, I keep getting the error message. Please help. Error in colMeans(x, na.rm = TRUE) : 'x' must be an array of at least two dimensions The codes are: data2_1 <- matrix(c(0.9584190, 0.2710325, -0.9495618, -0.1301772, -0.7539687, 0.5344464, -0.8205933, 0.1581723, -0.5351588, 0.04448065, 0.9936
