Alexandre, The output from corr.test is a list of matrices. To export one of those matrices, simply specify which one you want:
Using the example from my previous note: > library(psych) > examp <- corr.test(sat.act) > mat.c.p <- lower.tri(examp$r)*examp$r + t(lower.tri(examp$p)*examp$p) > mat.c.p mat.cp is a matrix and can be directly written using write.table (if you want). To find out what are the elements of the list produced by corr.test, use the str command; str(examp) will produce List of 5 $ r : num [1:6, 1:6] 1 0.0873 -0.0209 -0.0365 -0.0188 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : chr [1:6] "gender" "education" "age" "ACT" ... .. ..$ : chr [1:6] "gender" "education" "age" "ACT" ... $ n : num [1:6, 1:6] 700 700 700 700 700 687 700 700 700 700 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : chr [1:6] "gender" "education" "age" "ACT" ... .. ..$ : chr [1:6] "gender" "education" "age" "ACT" ... $ t : num [1:6, 1:6] Inf 2.314 -0.551 -0.965 -0.498 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : chr [1:6] "gender" "education" "age" "ACT" ... .. ..$ : chr [1:6] "gender" "education" "age" "ACT" ... $ p : num [1:6, 1:6] 0 0.0209 0.5818 0.3349 0.6187 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : chr [1:6] "gender" "education" "age" "ACT" ... .. ..$ : chr [1:6] "gender" "education" "age" "ACT" ... $ Call: language corr.test(x = sat.act) - attr(*, "class")= chr [1:2] "psych" "corr.test" To export one of those as a text file you could just copy the output, or you can write.table one element. e.g., write.table(examp$r) Bill On Nov 1, 2011, at 4:43 AM, AlexC wrote: > Hello, > > Thank you for your replies.
