Hello,
Maybe something like the following is what you want.
I have added an extra argument 'fill' to allow to choose what to print
in the end. It's default value is "" making the entire matrix elements
characters but it can be NA or 0.
print0 <- function(x, len = 10, digits = 2, fill = ""){
n <- length(x)
x <- round(x, digits = digits)
passes <- n %/% len
remainder <- n %% len
A <- matrix(fill, nrow = passes + (remainder > 0), ncol = len)
for(i in seq_len(passes)){
A[i, ] <- x[(len*(i - 1) + 1):(len*i)]
}
A[nrow(A), 1:remainder] <- x[(len*passes + 1):n]
A
}
print0(rnorm(23), 10)
print0(rnorm(23), 10, fill = 0)
Hope this helps,
Rui Barradas

Dear All:
Below is what I meant. Procedure print0 allows me to print a vector of
length 53 in four rows of 10 plus 1 row of 3 (Ido not like the NA). This
is silly. I am hoping that there is a candid way to print the matrix.
Thank you.

Is there a convenient way to print a vector into rows of a specified
column length? What I need is to print in the old FORTRAN format, viz.,
format(10F8.2)
which would print, for instance, a vector of 25 into two rows of 10
plus an incomplete row of 5. I managed to write a procedure for that
task, as shown below (except that I prefer simply blanks rather than
the NA). I am too embarrassed to even show the procedure. In short, I
like to print in the above FORTRAN format. Thank you.
