I have a data frame named all_cars containing 1082 rows and 1583 columns. Each row represents an observation; each column represents a variable. Every data value is an integer or decimal value; there are no nulls or non-numeric strings. I want to use the tilting library to do variable selection. I enter a command like
> all_cars_tilt <- tilting(all_cars[,10:20], all_cars[,2], op=2) and get the response Error in t(X[, active, drop = FALSE]) %*% X[, active, drop = FALSE] : requires numeric/complex matrix/vector arguments If I try the command with a larger range of X variables (say 6:384), the command seems to hang. I have run spikeslab on the same data set (columns 6:384 as X, column 2 as Y), without difficulty. Can anyone help me interpret the error message? Thanks!
