Dear all, I have a problem with the cat() function. Let say I have following:
fn1 <- function(n = 5){
mat <- matrix(rnorm(5*5), 5, 5)
cat(as.character(mat))
return(n)
}
However when I run above function I get this:> fn1()
-0.601930631438248 -1.16950049447942 0.469257329394626
-1.39766868242906 -1.02580943892082 1.4067931110327 -1.07245318857022

0.221592557337622 -1.91535929883353 -0.712994991755814
-0.440738636680476[1] 5
How can I preserve the "matrix" format while printing?
Thanks,
Hello,
If it does not *have* to be cat(), this would work:
fn1 <- function(n = 5){
mat <- matrix(rnorm(5*5), 5, 5)
print(mat)
return(n)
}
Cheers,
Josh

Dear all,
I planning to carry out a content analysis in R but I don't know which
package
to use.
I tried rqda (http://rqda.r-forge.r-project.org/index.html) but it doesn't
help.
Any suggestion will be appreciated.

Try the following:
fn1 <- function(n = 5){
mat <- matrix(rnorm(5*5), 5, 5)
cat(print(mat))
invisible(NULL)}

What is the problem that you are trying to solve?
It is still visible even it is set invisible(NULL):> fn1 <- function(n = 5){+ mat <- matrix(rnorm(5*5), 5, 5) + cat(print(mat)) + invisible(NULL)}> fn1()[,1] [,2] [,3] [,4] [,5] [1,] -1.22767085 -1.41468587 -2.0156231 0.29732942 0.5755600 [2,] -0.16775996 -0.03780596 -0.9461079 0.91289175 0.1254273 [3,] 0.09696032 -0.75522210 -0.7494442 -0.21341669 1.7088194 [4,] 0.13535505 -1.09011005 -0.6074198 0.05342614 -1.1996344 [5,] 0.66474083 -2.62206248 0.1329972 0.06132865 0.5124778 -1.227671 -0.1677600 0.09696032 0.1353550 0.6647408 -1.414686 -0.03780596 -0.7552221 -1.09011 -2.622062 -2.015623 -0.9461079 -0.7494442 -0.6074198 0.1329972 0.2973294 0.9128917 -0.2134167 0.05342614 0.06132865 0.57556 0.1254273 1.708819 -1.199634 0.5124778>>-- View this message in context: http://r.789695.n4.nabble.com/Problem-with-cat-tp2538811p2539551.html Sent from the R help mailing list archive at Nabble.com.
