Re: [R] Application of R
No Excel attachment came through. Just taking a guess here but there seems to be very little variation the columns V10 till column V23. BTW, can you not issue the following call : mydata[ , 1:7] ~ mydata[ , 8] + mydata[ ,9] instead of creating y1, y2, ... separately then cbind-ing them ?

[R] Application of R
I have applied the R and MNP to carry out the data analysis. However, there is an error called SWP : singular matrix. Can someone tell me what is the problem of my formula or the file "mydata". I have attached the data file "mydata" in Excel format and the result printed in pdf format for your information.

[R] Application of R with Multinomial Probit Model
Dear All, I still cannot solve the error (see attached printed pdf file). Can somebody give me some advice? I have also attached my data file in Excel and text formats for your reference. I have already assigned the y1,y2,x1,x12,z1,z2.z14 as V1V23 but still can't work. Please try out and advise. Thanks.

Re: [R] Application of R
Hi I do not know anything about mnp but the variables in your data frame has names V1:V23 and you request mnp to use variables x1..., y1..., and z1 Unless you have them somewhere, where do you suppose mnp to know about them? Try to read some basic text about data structures and manipulation with them e.g. R-intro.pdf which is probably in doc directory.

Re: [R] Application of R and MNP
Dear Andy, You appear to have 7 observations and 8 explanatory variables in the model. You'd be in trouble even if this were a linear model fit by least squares. Moreover, each observation has a different value of the response variable -- that, is the response has 7 levels. Did you really intend to do that? Perhaps it would help to know what you want to do with these data. I hope this helps, John John Fox Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604 http://socserv.mcmaster.ca/jfox > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Andy Wong > Sent: Sunday, January 22, 2006 9:55 AM > To: r-help@stat.math.ethz.ch > Subject: [R] Application of R and MNP > > Dear all, > > I'm a new user of R and MNP.

[R] Application of R and MNP
Dear all, I'm a new user of R and MNP. Would anybody advise me what I have done wrong to the input or data. When I add the R7, it said that there is an error "SWP:singular matrix". I can add up to R6 only. Copy of the R console is attached for your reference. Thanks.
