Data files is pretty vague. If you save the output of a function such as
rcorr(), you can extract any of the parts you need. Step 1 is to read the
documentation:
?rcorr
Under the section labeled "Value" you will see that rcorr() returns a list with
3 matrices named r, n, and P:
> Y <- rcorr(as.matrix(X))
> str(Y)
List of 3
$ r: num [1:3, 1:3] 1 -0.934 -0.814 -0.934 1 ...
..- attr(*, "dimnames")=List of 2
.. ..$ : chr [1:3] "mpg" "cyl" "disp"
.. ..$ : chr [1:3] "mpg" "cyl" "disp"
$ n: int [1:3, 1:3] 5 5 5 5 5 5 5 5 5
..- attr(*, "dimnames")=List of 2
.. ..$ : chr [1:3] "mpg" "cyl" "disp"
.. ..$ : chr [1:3] "mpg" "cyl" "disp"
$ P: num [1:3, 1:3] NA 0.0201 0.0937 0.0201 NA ...
..- attr(*, "dimnames")=List of 2
.. ..$ : chr [1:3] "mpg" "cyl" "disp"
.. ..$ : chr [1:3] "mpg" "cyl" "disp"
- attr(*, "class")= chr "rcorr"
> Y$r
mpg cyl disp
mpg 1.0000000 -0.9341083 -0.8138289
cyl -0.9341083 1.0000000 0.9342174
disp -0.8138289 0.9342174 1.0000000
> Y$n
mpg cyl disp
mpg 5 5 5
cyl 5 5 5
disp 5 5 5
> Y$P
mpg cyl disp
mpg NA 0.02010207 0.09368854
cyl 0.02010207 NA 0.02005248
disp 0.09368854 0.02005248 NA
You can save the whole list with save() or write individual matrices as .csv
files with write.csv().

Subject: [R] How can output tables be converted to data files?
Hi R'ers:
This code produces: 3x3 rcorr matrix, one-element vector, and 3x3
p-value matrix.
I would like to use these outputs as data files.
How can these output tables be converted to data files?
Any assistance is appreciated.
Thanks. Bruce
library(Hmisc)
mtcars5 <- mtcars[sample(1:nrow(mtcars), 5, replace=FALSE),]
X<- as.matrix(mtcars5[, c(1,2,3)])
print(X)
rcorr(as.matrix(X))
