Hello Dear, I have a function, like z=f(x,y), and try a surface plot with this function. But, on the reference of "wireframe" requires data option, so I generated x and y, and computed z with them. But, still I have a problem to draw a surface plot. The code and errors are ################################################## mle_beta0=64.43707; mle_beta1=-24365.16; # generating for

Crosstabs in R
Before I reinvent the wheel, I have need for a relatively straightforward crosstabulation (2 x n) function. I know that R has table(), ftable(), xtabs(), and summary(xtabs()), but none of these produce a fully "tricked" out cross-tabulation with marginal totals, expected cell frequencies, and an array of statistics about the contingency table. Is there a more complete (something

read.spss Error reading system-file header
Is there any documentation on what kind of SPSS file can and cannot be read by read.spss? Alternatively, how can one modify or "clean" an SPSS file to make it readable by read.spss? What properties must a *.sav file before read.spss can read it? The file in this example is 270KB, with 5 rows and 173 columns. I have no trouble reading larger files with read.spss, so it's not

Can I make spss.get reencode from Windows-1252?
Hi all. I have an SPSS file that I'm loading into R with the Hmisc spss.get function. The trouble is that the SPSS file uses the Windows-1252 character set (which I think is the default for SPSS on Windows) instead of plain-ol' Latin-1, and since spss.get doesn't allow me to pass the "reencode" option to read.spss, any characters in Windows-1252 that are not a part of Latin-1

SPSS R-Menu for Ordinal Factor Analysis
Dear all, I am trying to conduct an enhanced version of factor analysis with a SPSS interface that allows to use R. This approach has been suggested in the recent article: Basto, M. and J.M. Pereira An SPSS R-Menu for Ordinal Factor Analysis. Journal of Statistical Software 46, pp. 1-29. My variables are ordinal-type and the tool of Basto allows to run polychoric correlations in the SPSS

How can I import user-defined missings from Spss?
Hi, It works for me to import spss datasets via library(foreign) with read.spss or via library Hmisc by (spss.get). But no matter which way I do import the data, user-defined missings from Spss are always lost. (it makes no difference if there are a single value, a range, or any combination of them. They are always ignored). Is there any way in R to find out if any value was user-defined missing

SPSS and R – do they like each other?
Hi, I wonder how well SPSS and R communicate, because I need SPSS but would like to do some data manipulations in R. However I am very afraid of never ending import-export-complications ? especially with all those labels and extra information my SPSS files contain. My data come from SPSS and have to be exported to SPSS again (because I need to produce special output tables, which would be hard to

read.spss doesn't work anymore
A couple of months ago, probably using an older version of R, R used to run the following code just fine: library("foreign") data.exp1 <- as.data.frame(read.spss("dataDef.sav")) Issuing the same commands now (after starting R using --vanilla), gives me the following behavior: > library("foreign") > x <- read.spss("dataDef.sav") Error
