[R] mlogit.optim start values problem

Hello All, I received the following message and I think it is regarding start values or the method. semsem = mlogit.optim ( LL=LL*Prob[i,1] , start = c(1,1,1), method = c("bfgs"), iterlim = 2000, tol = 1E-05, ftol = 1e-08, steptol = 1e-10, print.level = 2) + + } Error in as.name(f[[2]]) :

Re: [R] "haven" - read_spss: How to avoid extracting value labels instead of long labels?

Looks like a little bug in 'haven': When I actually look at the attributes of one variable that has no long label in SPSS but has Value Labels, I am getting: attr(spss1$WAVE, "label") NULL But when I sapply my function longlabels to my data frame and ask it to print the long labels for each

Re: [R] "haven" - read_spss: How to avoid extracting value labels instead of long labels?

I have to rephrase my question again - it's clearly a small bug in haven. Here is what it is about: If I have a column in SPSS that has BOTH a long label and value labels, then everything works fine - I access one with 'label' and another with 'labels': attr(spss1$MYVAR, "label") [1] "LONG

Re: [R] Compute Regressions with R-Function

No function is necessary for multiple lhs's. lm() allows a matrix as it's lhs and will fit a separate regression for each column of the matrix. Please read ?lm carefully for details. For that matter, please read the linked Help pages and/or spend some time with a tutorial (there are many on the

Re: [R] recursive partitioning in R

Look at the rpart vignette "User written split functions". The code allows you to add your own splitting method to the code (in R, no C required). This has proven to be very useful for trying out new ideas. The second piece would be to do your own cross-validation. That is, turn off the

Essentially the problem is related to this problem. I am measuring the fluorescence (flu) generated over time (clock) from 5 samples (samp) which are grouped by two targets (targ). I can calculate the variance of the fluorescence for each sample at a given time (in this example, for sample 1); but

Hi Alaa, >From the code you sent, I think that the error may be in one or more lines preceding the call to mlogit.optim. The "+" prompt means that the R interpreter thinks there is more to come, and when you added a right brace ("}"), it probably tried to interpret everything back to the last left

You may have additional scoping problems depending on where you various variables exist, but your Trend function syntax is incorrect. You need parentheses around your arguments to the lm call, and you left out the '~' in your formula. In addition, don't fool yourself by your use of the names
