fill

The initializing fill value for the empty matrix.

mode

Examples

# NOT RUN {
invec <- c("1,2,4,5,6", "1,2,4,5,6", "1,2,4,5,6",
           "1,2,4,5,6", "-1,1,2,5,6", "1,2,5,6")
A <- strsplit(invec, ",")
splitstackshape:::numMat(A)
splitstackshape:::numMat(A, fill = 0)
splitstackshape:::numMat(A, mode = "value")
