Good working knowledge of a DBMS is almost invaluable when it comes to working with very large data sets. In addition, learning SQL is piece of cake compared to learning R. On top of that, knowledge of another (SQL)

Hi everyone, i?m trying to graphically display distributions with r and i?m working with makrodata from the WVS. the command i?m using is > plot (Makrodata$v11, Makrodata$v12, xlab="Democracy Score Economist", > ylab= share religious people") i?m having an additional variable that identifies respectively labels the

In this case the environment contains the variables local to the function, and its enclosure is the environment of the enclosing function.(R-lang:p11) I want to know if the "enclosing function" means the closure of the function? for example ,if I call function mean(),and the create an environment,say e1,then the enclosure of e1 is the namespace of base package? Right? Thank you!

Hi, Given a frame with calendar date's: "2005-07-01", "2005-07-02","2005-07-03","2005-07-04","2005-07-05",etc. I want to extract the following from these dates: week number month number year number Any ideas how to accomplish this? Many thanks. Regards, Richard

... and is there also such a nice tool (like spss.get) for exporting data frames to SPSS? write.table does not keep the data frame labels - neither did the other exporting tools that I found. Thanks! Michael [[alternative HTML version deleted]]

The incorrect result incurs when the file path contains Chinese character. It seems that dirname/basename action on unit of byte instead of char, so the result in the following example is half of what is expected. > g<-"d:\\$BG!2L4^M-CfJ8(B\\$BG!2L4^M-CfJ8(B.txt" > dirname(g) [1] "d:/$BG!2L4^(B" > basename(g) [1] "$BG!2L4^M-(B" -- HUANG Ronggui,

What I want to do is: 1, creat a text box, insert text into that box. 2, select chunk of of the text by mouse, and link it to a lable. so I would like a way to get that chunk of text. Can I do such job with tcltk? Any relavant tutorial materials?

Hello. I am trying to pull out one country from a time series of 5 waves. For example I need Norway from the 5th wave. This is new to me. Typically, I work with country specific surveys. data = norway I have attached a .tiff of the codebook showing the variable names for Norway and the wave. They appear to be Norway = v218 and wave = v15. But perhaps I am wrong and this is part of the

Hi, is there any other routine for factor analysis in R then factanal? Basically I'am interested in another extraction method then the maximum likelihood method and looking for unweighted least squares. Thanks in advance Sigbert Klinke

i use the CrossTable (frome gregmic package) function to get such a table as below. but the percentage of the non-NA levels(here 1,2,3,4,5) is not totally 100%. is there any way to get a table that percentage of the non-NA levelsis totally 100%,as the SPSS' valid percentage.thank you!

It is not a pure R question,but I hope some one can give me advices. I want to use analysis my data with the multilevel model.The data has 2 levels---- the second level has 52 units and each second level unit has 19-23 units.I think the sample size is quite small,but just now I can't make the sample size much bigger.So I want to ask if I use the multilevel model to analysis the data set,will

I want to get the logLik to calculate McFadden.R2 ,ML.R2 and Cragg.Uhler.R2, but the value from multinom does not have logLik.So my quetion is : is logLik meaningful to multinomial logistic model from multinom?If it does, how can I get it? Thank you! ps: I konw VGAM has function to get the multinomial logistic model with logLik, but I prefer use the function from "official" R

I have a string vector like these: [1] "1-1-1" "1-1-2" "1-2-1" And I wanna replace the second "-" with "0", that is, I wanna get the result like: [1] "1-101" "1-102" "1-201". How should I write the Regular Expressions? Thanks! -- »ÆÈÙ¹ó Department of Sociology Fudan University [[alternative HTML version deleted]]

SPSS seems to have changed its default datafile format, resulting in issues for read.spss(). In Windows this results in a warning, in Debian the import completely fails: Debian (R version 2.8.0 (2008-10-20) i486-pc-linux-gnu, foreign_0.8-29) > read.spss("/home/jeroen/samples/Tomato.sav") Error in iconv(names(rval), cp, "") : unsupported conversion from 'CP65001'
