[R] print matrix values and if statement

[jim holtman]

Here is how to get the indices of the non-zero values.  You can
determine how you want to print them

> x <- rbind(c(1,0), c(0,3))
> # get indices of non-zero
> which(x != 0, arr.ind=TRUE)
     row col
[1,]   1   1
[2,]   2   2

possible ways of printing:

> x.1[x.1 == 0] <- NA
> x.1
     [,1] [,2]
[1,]    1   NA
[2,]   NA    3
> print(x.1, na.print='.')
     [,1] [,2]
[1,]    1    .
[2,]    .    3
