Attention R users, especially those that are experienced enough to be opinionated, I need your input. Consider the following simple plot: x <- rnorm(100) y <- rnorm(100) plot(x, y, bty='n') A colleague (and dreaded SAS user) commented that she thought that my plots could be "cleaned up" by connecting the X and Y axes. I know that I can do that with bty='l' but I

Dear Rusers, I have met a difficult problem on explaining the differences of principal component analysis(PCA) between R,S-PLUS and SAS/STATA/SPSS, which wasn't met before. Althought they have got the same eigenvalues, their coeffiecients were different. First, I list my results from R,S-PLUS and SAS/STATA/SPSS, and then show the original dataset, hoping sb. to try and explain it.

Good morning, I use SAS and R/S-Plus as my primary tools so I have a lot of experience with these programs. By far and away, SAS is superior for handling the "messy" datasets, but also the very large ones. I work at times with datasets in the hundreds of thousands (and on occasion, millions) of records. SAS, and especially PROC SQL, are invaluable for this. But once I get to

I am brand new to R and would like to know if there is a way to be able to create, save and retrieve a program in R like a script object in S-Plus. I am just not sure how to do this. I'm sure there are many ways to do this ranging from simple to complex, but the simplest way would be best for me. Thanks, in advance... __________________________________________________ Y!

Apologies in advance from an R newbie if this is a dumb question. Is it possible to produce choropleth maps in R? I gather from some nice research papers on the AT&T (sorry, Lucent) S web site that in S (and S Plus) there is a map() function which uses arrays of polylines and regions to draw map borders and then fill them with patterns or shades according to some scalar quantity. We currently

Hi all, if you do not have a SAS license but want to convert native SAS data files, the solution below will work. # read SAS data without SAS # 1.

Hi: For those of you who are adept at both SAS and R, I have the following questions: a) What are some reasons / tasks for which you would use R over SAS and vice versa? b) What are some things for which R is a must have that SAS cannot fulfill the requirements? I am on the ramp up on both of them. The general feeling that I am getting by following this group is that R updates to the product are

I have 3 SAS files all in the directory F:/sas, two data files and a format file : form.ea1.sas7bdat form.ea2.sas7bdat sas.fmts.sas7bdat F is a USB. I am trying import them to R using "sas.get". I have not used SAS since I was downloading data from mainframe and having to write JCL. I had forgotten how bizarre SAS can be. I currently have not even figured out how to load the files

I hope this is merely a FAQ, and not an AFAQ (annoyingly....). I'm a SAS programmer, with several years' experience of the system, evaluating alternatives. See the SAS for Linux website (URL in sig) for more info. I'm exploring R's capabilities and limitations. I'd be very interested in having a deeper understanding of it capacity and performance limitations in dealing with

Hello All, ? Am replicating in R an analysis I did earlier using SAS. See this as a test of whether I'm ready to start using R in my day-to-day work. ? Just finished replicating a Kaplan Meier analysis. Everything seems to work out fine except for one thing. The 95% CI around my estimate for the median is substantially larger in R than in SAS. For example, in SAS I have a median of 3.29 with a

Hi, First-off, I apologize if this is the wrong list to post to, but I would like to install and try out 'R', as an alternative to 'SAS' . As a newbie, could you pl let me know about the following (in terms of online resources and print books) I have previously used SAS/BASE in a Biostatistics/ Epidemiology (Public Health) class, and familiar with very basic terminology and

I am attempting to read in a SAS 9.1 data file. After starting R I change to the directory containing the sas data file and use the "dir" command to confirm that it is there. Then I run the following R-code: library(foreign) sashome <- "/Program Files/SAS/SAS 9.1" test<-read.ssd(file.path(sashome), "pcb", sascmd = file.path(sashome,

Hi R, Suppose that SAS dataset 'tsubset1' is stored in the path, "Z:/data". Then I give the below read.ssd() command to read SAS dataset, 'tsubset1.sas7bat' into R. > library(foreign) > s=read.ssd("Z:/data","tsubset1",sascmd = "C:/Program Files/SAS/SAS 9.1/sas.exe") > s A B C 1 3 4 5 2 6 7 8 3 3 4 5 It reads

Hi! I need to import in R some SAS dataset (sas7bdat). I found two functions to do it: "read.ssd" from the package "foreign" and "sas.get" from "Hmisc". df = read.ssd(libname = path2data, sectionnames = "sasSmallDataset", tmpXport = path2data, tmpProgLoc = path2data, sascmd = path2sas) sas.get(libraryName = path2data, member =

Hi, I am trying to read a SAS version 9.1.3 SAS dataset into R (to preserve the SAS labels), but am unable to do so (I have read in a CSV version). I first created a transport file using the SAS code: libname ces2 'D:\CES Analysis\Data'; filename transp 'D:\CES Analysis\Data\fadata.xpt'; /* create a transport file - R cannot read file created by proc cport */ proc

Dear all, I am trying to import a SAS file into R (in fact I only need the value labels from the formats file), using Hmisc package, but I get this error: my.sas <- sas.get("/home/adi/3", "fis1_sgg") sh: sas: not found Error in sas.get("/home/adi/3", "fis1_sgg") : SAS job failed with status 32512 I read some past discussions and I get the impression

Hello, I'm trying to import a SAS file made using SAS on Unix. Currently I'm using SAS on Windows and I'm trying to import that .ssd04 file to R. The file name of the file is testfile.ssd04 and it is located in 'M:\sasuser'. I'm using Windows XP and R 2.91. Basically what I'm doing is ############ r code ############## > library(foreign) > sashome <-

Yesterday I just noticed the new document on R and regulatory aspects for biomedical research posted at http://www.r-project.org/doc/R-FDA.pdf Coming from an institution that performs a large number of clinical trials for FDA and being an advocate of R myself, I have found that the following issues usually come up when discussing the use of R for FDA trials: 1. Most FDA submissions come down to

Hi, I am encountering a confusing problem when I tried to use read.ssd to read SAS datasets. For one SAS dataset "a.sas7bdat", it did not work; while for another SAS dataset "b.sas7bdat" it worked: > tmp<-read.ssd("C:\\SASdata", "a",sascmd="C:/Program >Files/SAS/SASFoundation/9.2/sas.exe") SAS failed.
