Yes it certainly isn't an easy question to answer, and I don't necessarily need complete data. The situation as presented to me by my colleagues in the Social Sciences is really that SPSS is the standard, so I am basically hoping for evidence to just shake this view (unless it is true, but I have to say I doubt it). I am more hoping for particular examples of cases in the Social Sciences, where SPSS is far from the standard, and the programs and schools you mention below are exactly the sort of thing I was looking for! I think it is not the standard -- often unheard of -- by the social science community in large research universities in the States where SAS dominates (unless you are in the Chicago area). So I agree with John. It is perhaps more popular among social scientists in Europe. For now unfortunately we will be sticking with SPSS, despite the considerable cost (which was mainly our problem at the moment, so SAS is not even being considered for that reason), but I am hoping to slowly build enough evidence of the extensive use of R for when all this comes up again. Even just a list of the universities and departments that use it would be very helpful, so any of you who would like to send such information about your departments or other departments you might know about, off the list, it would be extremely helpful to me. Perhaps it would be useful for such a list to exist somewhere online? (I guess you could say google, but I find it hard to use google to look up such information on R, for the obvious reason of the shortness of the name. [snip] Among social scientists the picture is not as clear. My impression is that SPSS is used very widely for low-levels methods courses taught to undergraduates, and not very extensively in the best social-science graduate programmes. I would expect that, at present, Stata use in social- science graduate programmes exceeds R, and that SAS and R would also be used fairly widely. In my opinion, these are the only reasonable choices -- I don't think that SPSS is sufficiently capable to compete with R, Stata, or SAS. There are, for example, several different packages used at the ICPSR Summer Program in Quantitative Methods for Social Research, but several relatively advanced courses now use R. Likewise, the Oxford Spring School, hosted by the Department of Politics and International Relations at Oxford, has mostly employed R and Stata. Thanks, I will be looking into those. I basically just need to look at various universities and their social sciences departments, and see what they use there. As other suggested, I will be looking into the number of books and papers in R and how it is increasing every year. Once again thank you all for your comments, this has been a very helpful discussion for me, and it's a great pleasure to find such a helpful and friendly mailing list.

Re: [R] A comment about R:
Dear Bob, The reasons you mentioned are supposedly good features in R -- not giving lots of output you do not necessarily need. I guess the question is why do you want R to produce what you get from SPSS? SPSS is hardly a gold standard in statistical software. But I agree that it is quite difficult for users of SPSS to unlearn SPSS (or SAS) while using R. Best Marwan -- Marwan Khawaja http://staff.aub.edu.lb/~mk36 -- -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Green Sent: Wednesday, January 04, 2006 3:37 AM To: r-help@stat.math.ethz.ch Subject: Re: [R] A comment about R: Hello, Unlike most posts on the R mailing list I feel qualified to comment on this one. For about 3 months I have been trying to learn use R, after having used various versions of SPSS for about 10 years. I think it is far too simplistic to ascribe non-use of R to laziness. This may well be the case for some, however, I have read 5-6 books on R, waded through on-line resources, read the documentation and asked multiple questions via e-mails - and still find even some of the basics very difficult. There are several reasons for this: 1. For some tasks R is extremely user-unfriendly. Some comparative examples: (a) In running a chi-square analysis in SPSS the following syntax is included /STATISTIC=CHISQ /CELLS= COUNT EXPECTED ROW COLUMN TOTAL RESID . this produces expected and observed counts, row column percentages, residuals, chi-square Fisher's exact test + other output. In R, it is a herculean task to produce similar output . It certainly, can't be produced in 2 lines as far as I can tell. (b) in SPSS if I want to compare multiple variables by a single dependent variable this is readily performed CROSSTABS /TABLES=baserdis baserenh basersoc baseradd socbest disbest entbest addbest worsdis worsphy by group I used the chi-square example again, but the same applies for a t-test. I started looking into how to do something similar in R, with the t-test command but gave up. R does force the user to take a more considered approach to analysis. (c) To obtain a correlation matrix in R with the correlation p-value is no simple task - In SPSS this is obtained via: GET FILE='D:\a study\data\dat\key data\master data.sav'. NONPAR CORR /VARIABLES= goodnum badnum good5 bad5 avfreq avdayamt /PRINT=KENDALL TWOTAIL /MISSING=PAIRWISE . In R something like this is required - by(mydat, mydat$group, function(x) { + nm - names(x) + rho - matrix(, 6, 2) + rho.nm - matrix(, 6, 2) + k - 1 + for(i in 2:4) { + for(j in (i + 1):5) { + x.i - x[, i] + x.j - x[, j] + ct - cor.test(x.i, x.j, method=c(kendall) , alternative + =c(two-sided)) rho[k, 1] - ct$estimate rho[k, 2] - + round(ct$p-value, 3) rho.nm[k, ] - c(nm[i], nm[j]) k - k + 1 } } rho + - cbind(as.data.frame(rho.nm), as.data.frame(rho)) + names(rho) - c(freq.i, freq.j, cor, p-value) rho + }) 2) It is not always clear what the output produced by R, is. The Mann-Whitney U-test is a good example. In R, it seems a standardised value is obtained. I was advised that it is easy enough to check this as R is open-source, but at least for me, I don't believe I would understand this code anyway. It is confusing when comparative programs such as R and SPSS produce dis-similar results. For the user it is important to be able to fairly easily reconcile such differences, to engender confidence in results. 3) I find the help files in R quite difficult to understand. For example, see help(t.test). It is almost assumed by the examples that you know what to do. Personally, I would find some form of simple decision tree easier -e.g. If you want to perform a t-test with the dependent variable in one column and the dependent use in another use t.test(AVFREQ~GROUP) . If you want to perform a t-test with the dependent variable in separate columns (each column representing a different group) use - t.test(AVFREQ1, AVFREQ2) . 4) My initial approach to using R, was to run commands I had used commonly in SPSS and compare the results. I have only got as far as basic ANOVA. This has been time-consuming and at times it has been difficult to obtain advice. Some people on the R list have been extremely generous with their time and knowledge, and I have much appreciated this assistance. At other times I see responses met with something like arrogance. With the sophistication of R, there is also an elitism. This is a barrier to R being more widely accepted and used. 5) differences in terminology - this is just part of the learning process, but I still found it took quite some time to work out simple commands and what different analyses were called. 6) system

[R] mca
Dear All, I want to 'impose' supplementary points to an mca plot -- using VR MASS library -- and I wonder if anyone had any luck. The book (4th edition) says it can be done using predict.mca but there are no examples provided in the help pages. Would appreciate any help/pointers. Thanks Marwan btw, to Professor Ripley -- the abbrev=TRUE option for labels does not seem to work.

[R] survey package
This is great! Thanks Thomas! Marwan -Date: Sat, 25 Jan 2003 11:55:12 -0800 (PST) -From: Thomas Lumley [EMAIL PROTECTED] -To: [EMAIL PROTECTED] -Subject: [R] survey package -A new package `survey' for analysing complex survey samples is on CRAN. I-t handles stratification, clustering, and unequal sampling probabilities -in descriptive statistics, glms, and general maximum likelihood fitting. -The package is still under development: - - it doesn't do the finite population correction to variances - - it needs some real life worked examples -Most importantly, though, I don't do this sort of analysis routinely, so -it's possible that some part of the interface is completely insane from -the viewpoint of practising survey statisticians.

[R] Using Internet proxies
Hi, I want to thank Prof Ripley for his very helpful suggestions re internet proxies. This is great -- very useful! Marwan -- Marwan Khawaja http://webfaculty.aub.edu.lb/~mk36 if you have MS Explorer -- From: [EMAIL PROTECTED] Date: Wed, 22 Jan 2003 19:07:42 + (GMT) To: [EMAIL PROTECTED] Subject: [R] Using Internet proxies There have been quite a few questions recently about this, so I have tried to gather experience. I set up a proxy using Apache2 (a very common server) behind our firewall and tried various authentication approaches. One comment: all the methods return error messages when they fail. Please don't report `it doesn't work' without the full details. 1) For a proxy that authenticates at most by hostname/IP address, and for Windows users, just set up IE6 to work, and use the --internet2 command-line flag. This worked for me (despite various claims here). 2) For a proxy that authenticates at most by hostname/IP address, the internal download.file method works, provided you set the environment variable http_proxy or HTTP_PROXY correctly, e.g. in ~/.Renviron. This is almost of the same form as used by wget, but is less tolerant, and note that setting `no_proxy' disables the proxy for all sites (unlike for wget). 3) If you have a proxy that demands that you enter a username/password combination, you can use the internal download method in R-devel: see ?download.file. 4) Installing wget and using the options(download.file.method=wget) provides a highly tunable approach. For Windows users, wget is still available on http://www.stats.ox.ac.uk/pub/Rtools. Note that none of these methods support proxies that want more advanced methods of authentication, e.g. Digest under HTTP/1.1. If there are any such proxies, please can a user provide us with a proven method. -- Brian D.
