Re: [R] automating regression or correlations for many variables

Thanks! I must confess I am just a beginner, but I followed your suggestion and did 'm <- lm(as.matrix(snp[, -1]) ~ lat, data = snp) ' and it worked perfectly. I would like to understand what is being done here. as.matrix I understand makes my data frame be a matrix, but I don't understand the pa

Hi: Here's a small example: > df <- data.frame(y1 = rnorm(10), y2 = rnorm(10), y3 = rnorm(10), lat = rnorm(10)) > m <- lm(cbind(y1, y2, y3) ~ lat, data = df) > summary(m) The LHS of the model formula needs to be a matrix. In your case, something like m <- lm(as.matrix(snp[, -1]) ~ lat, data =
