Which you would have known had you read the docs!

Thomas, thanks for the cool trick. I always thought browser() was the
only thing existed, apparently not.

Re: [R] What does this say? Error in rep("(Intercept)", nrow(a0)) : invalid 'times' argument
Mike-
You can use the traceback function to see where the error is:
> bob <- matrix(rnorm(100*180), nrow=180)
> yyy <- rnorm(180)
> fit1 <- cv.glmnet(bob, yyy, family="mgaussian")
Error in rep("(Intercept)", nrow(a0)) : invalid 'times' argument
> traceback()
6: predict.multnet(object, newx, s, type, exact, offset, ...)
5: predict.mrelnet(glmnet.object, type = "nonzero")
4: predict(glmnet.object, type = "nonzero")
3: lapply(X = X, FUN = FUN, ...)
2: sapply(predict(glmnet.object, type = "nonzero"), length)
1: cv.glmnet(bob, yyy, family = "mgaussian")
So, thee error is in the predict.multnet function. If you peak at that
function, you see where the function falls apart. It seems that the
function wants a0 to be a matrix but in this example it is a vector. I'm
not familiar enough with the package to offer advice on how to fix this.

[R] What does this say? Error in rep("(Intercept)", nrow(a0)) : invalid 'times' argument
Dear list,
I am using glmnet. I have no idea what this error is telling me.
Here's my code,
> bob <- matrix(rnorm(100*180), nrow=180)
> yyy <- rnorm(180)
> fit1 <- cv.glmnet(bob, yyy, family="mgaussian")
Error in rep("(Intercept)", nrow(a0)) : invalid 'times' argument
In fact, I peeked inside cv.glmnet() using,
> glmnet:cv.glmnet
Can't even find the error message in the code. I am clueless at the moment.
Thanks in advance,
Mike
