recommended way to group function calls in Sweave
...ld the actual calls be
used, after the replacement of arguments by their values:
'summary(iris[,1:2])' and 'cor(iris[,1:2])'.
Or is the recommended way to use cat()-ed statements:
f <- function(d, ind){
cat('Variable summary:\n')
print(summary(d[ , ind]))
cat('\nCorrelation table:\n')
print(cor(d[ , ind]))
return(invisible(NULL))
}
To obtain such output:
> f(iris, 1:2)
Variable summary:
Sepal.Length Sepal.Width
Min. :4.300 Min. :2.000
1st Qu.:5.100 1st Qu.:2.800
Median :5.800 Median :3.000
Mean :5.843 Mean :3.057
3rd Qu.:6.400...

A possible too old question on significant test of correlation matrix
Dear all,
I'm working on a data.frame named en.data, which has n cases and m columns.
I generate the correlation matrix of en.data by
> cor(en.data)
I find that there is no p-value on each correlation in the correlation
matrix. I searched in the R-help mail list and found some related
posts, but I didn't find direct way to solve the problem. Someone said
to use cor.test() or
