row.idx doesn't work ?

[Freequilibrium]

I try to split X,y by row.idx parameter in biglasso and cv.biglasso however when row.idx is been used, cv.biglasso will return error massage "錯誤發生在 E[cv.ind == i, 1:res$nl] <- res$loss： 被替換的項目不是替換值長度的倍數" sorry for chinese version massage, this massage more likely indicate that two lengths "E[cv.ind == i, 1:res$nl]" and "res$loss" are different

code

library(biglasso)

data("colon")

X <- as.big.matrix(colon$X)
y <- rnorm(62, mean=50)

tr.ind <- sample(length(y), length(y)*0.85, replace = FALSE)
tt.ind <- seq_len(length(y))[-tr.ind]

## With Error massage after cv.biglasso
mdl <- biglasso(X,y,row.idx = tr.ind, penalty = "lasso", family = "gaussian")
cv.mdl <- cv.biglasso(X,y,row.idx = tr.ind, nfolds = 10, penalty = "lasso", family = "gaussian")

## Without Error massage after cv.biglasso
tr.X <- as.big.matrix(colon$X[tr.ind,])
tt.X <- as.big.matrix(colon$X[-tr.ind,])

tr.mdl <- biglasso(tr.X, y[tr.ind], penalty = "lasso", family = "gaussian")
cv.tr.mdl <- cv.biglasso(tr.X,y[tr.ind], nfolds = 10, penalty = "lasso", family = "gaussian")
