I was using the glmnet package in R, and I saved my input x, as a csv file. Its dimensions are: 34 by 8.I saved the output variable y as another csv file, and its dimensions were: 34 by 1

Code: x <- read.csv("input.csv") y <- read.csv("output.csv")

  model = glmnet(x,y)

This shows the following error: Error in weighted.mean.default(y, weights) : 'x' and 'w' must have the same length

I even tried: as.numeric(unlist(y)), to make sure y is a vector, but it doesn't seem to work. Can someone please tell me the error in my format for the attributes?

share some data so that one can reproduce your problem. – abhiieor Jul 03 '16 at 10:18
check `NROW(x)` and `NROW(y)`: are they definitely the same? Also you are passing a dataframe, when `glmnet` expects a matrix: look at the help pages `?glmnet` – user20650 Jul 03 '16 at 12:13
For more specific help, you will need to edit your question with the results from `str(x)`, and `str(y)` – user20650 Jul 03 '16 at 12:14
Any pointers on how I could save x, and y as matrices instead? dim(x), and dim(y) show that both have same number of rows (=34). – 204 Jul 03 '16 at 12:19
