...u supply a small dataset that cause the error you are talking about? One way to do this is to use supply the results of dput(tbdata) if it is small enough. If not, maybe create a subset of the data and then use dput() Did you get the problem when you tried with the tutorial Bert suggested? > firstobs <- subset(tbdata, capture.ID == 'B1-1108') > firstobs <- firstobs[,c(1,2,2,3,4)] > colnames(firstobs) <- c('id', 'start.date','end.date','lat','long') > > ###change date format and change start date to previous 14 days > firsto...

1. You should always cc the list unless there is a clear reason not to. 2. You still have failed to follow the posting guide: You say you have difficulty troubleshooting your code, but you have shown us no code. You got an error message that seems explicit, but with neither code nor data, I do not know whether anyone can make sense of it. In any case, I certainly cannot. Cheers, Bert Bert

Hi...Can anyone help me for adding the second regressor to the FMOLS regresion. I am using the codes below. I could not succeed to write the correct sentence in place of the question marks. Do I need to make any changes in the source file also? I attached the original files published by Bruce Hansen. Thank you very much in advance for your precious help. Best Regards, Tarkan source

To Whomever is Interested, I have spent several days searching the web, help files, the R wiki and the archives of this mailing list for a solution to this problem, but nonetheless I apologize in advance if I have missed something obvious. The problem is this; I have a 5-column data frame with about 4.2 million rows, and want to create a new (and hopefully much smaller) data frame that

In the model: lm.1 <- lm(variable ~ BLOC + TIL * YEAR , data=selvanera) I found TIL*YEAR interaction significant. Then I am trying to compare means of the different levels of TIL inside every YEAR using: mc.2 <- glht(lm.1, linfct = mcp(TIL*YEAR="Tukey")) summary(mc.2, test = univariate()) but it does not work. There is any way of doing this, like the SLICE option in

as a r noob i am having another problem: i have a big dataframe where each row corresponds to one entry and each column is a field... for instance, i have the column ID and time and many more... Id like to get a dataframe where all IDs are just included once (some users with that ID might have several entries but Id like to kepp only one).. when i use unique I only get a list of the levels (or
