[R] Printing vector

[Steven]

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.

n<-53; x<-runif(n); # x<-round(x,2)

print0<-function(x,c=10,digits=2){
# ******************************************
# Print vector in rows of a specified length
# ******************************************
   n<-length(x)
   r<-n/c; if(n%%c>0) r<-as.integer(r)+1
   y<-rep(NA,r*c)
   y[1:n]<-x
   y<-matrix(y,r,c,byrow=T)
   y<-round(y,digits=digits)
   y
}

print0(x,c=10,digits=3)
