Hi guys, I am new to R, so sorry if my problem seems trivial. Sometimes I encounter some lists, which I cannot index their components with [ . ] For instance the prcomp() function returns a 'prcomp' object whose components are some 'lists'. the second component is a list that comtains the following: > mylist <- churn[2] > class(mylist) [1] "list" >

...do Principal Components Analysis, I am not very clear what is the "scale". And the scores are different from "PROC PRINCOMP" procedure from SAS. Using the example data from this package: restpc <- princomp(USArrests, cor = TRUE) > restpc$scale Murder Assault UrbanPop Rape 4.311735 82.500075 14.329285 9.272248 > sd(USArrests) Murder Assault UrbanPop Rape 4.355510 83.337661 14.474763 9.366385 Why 'restpc$scale' is different from 'sd(USArrests)'? felix

...Does anyone have any pointers how this might be accomplished? Thanks, Caleb ------- # Bigger example # Introduce artificial colinearity to test case P = cbind(USArrests[2]*2, USArrests) names(P) = c("Introduced", "Murder", "Assault", "UrbanPop", "Rape") # Split the data into partitions to be calculated separately # In the real case the full data would have been too large and # each instance would have received just a chunk of data.

Hi folks, I suspect this is a request for a sanity check than a bug report: I've been successfully compiling an optimised version of R for several years using the Intel compiler and MKL. I've just test-run the new Intel 15.0 compiler suite, and I'm seeing a few numeric failures that I don't see using the same build method with Intel 13.0. I've attached the output of

Hi, i found tis message in the archive and have got the same problems ? John, perhaps you have found now a way install RPgSQL for windows2000, or anybody other ? many thanks for advance christian [SNIP] I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or
