I have recently started learning R. I converted a Stata datafile into an R image file, but I am unable to do anything with the data. For example, I am unable to calculate the mean of any variable or create a scatterplot of some of the data. I always get a message saying, "Error in plot(rgnpc, incmean) : object "rgnpc" not found" when I attempt to make a simple plot of the two noted variables. I get the following when I attempt to get the mean of a particular variable: "Error in mean(incmean) : object "incmean" not found." What should I do?

Try ls() to get a list of the available objects. Dieter
Dear sir,
I have this persistent problem trying to use the lmer function.
After loading the lmer4 library and submitted my input command
Model1<- lmer(IndividualNum~BaitType*TrapType+( 1
|dTransect/dTrapStation/Expedition/Community), family=poisson(link=log))
It does fine but when I want it to display my model > >
summary(Model1) I get this strange error message.
Error in printMer(object) :
no slot of name "status" for this object of class "table"
What am I not doing right? And how can I rectify this problem.
Regards
Kwaku

Hello, Tell me please, can I get a sourcse code for 'lda' from MASS? Is MASS package still present in the latest R-2.6.2 version (I couldn't find it)? Thankful in advance, Alexey.
Hello, I have one more question. I looked through MASS.c file but I couldn't find lda(...) function here. I expected that 'lda' function is a part of MASS source code. Where can I find the source code for 'lda' - function? Best wishes, Alexey.
