I think you should be more suspicious of yourself, Dimitri. A letter T variable can easily arise in the problem domain when you are not thinking of logical values at all, at which point your cavalier use of T as a synonym for TRUE can suddenly become a bug. -- Sent from my phone.

...al - I shy away from using letters and words that "look familiar" to me in R (such as mean, sd, T, etc.) But still, it's a good advice.

.... above) And it's even slower because I have to do it step-by-step many times. Any way to do it by specifying all 3 delimiters at once ("aaa","_bbb","_ccc") and then split it in one swoop into a data frame with several columns? Thanks a lot for any pointers! -- Dimitri Liakhovitski [[alternative HTML version deleted]]

...on samples of up to N=700 but thousands and thousands of them. I am designing a simulation in R and running those regressions and R itself is way too slow. So, I am thinking of compiling the regression run itself in Fortran and Java and then calling it from R. Thank you very much for any advice! Dimitri Liakhovitski MarketTools, Inc.

Thanks Dimitris!!! That's much clearer now. Still have a lot of work to do this weekend to understand every bit but your code will prove very useful.

...to "turn off" the default tick marks and introduce those tick marks in specific locations. For example, currently in my X axis tick marks are (automatically) at 10, 11, 12, 13 but I want them to be in 5 specific locations, like 9.89, 10.34, etc. Any hint would be greatly appreciated! -- Dimitri Liakhovitski MarketTools, Inc.

To clarify: my question is not about "who could I exclude NAs from being counted" - I know how to do that. My question is: Why na.rm = T is not working for geom_bar in this case?

...uot;start"; e<-"end" middle<-as.character(c(1,2,3)) I would like to get the following result: "start 123 end" or "start 1 2 3 end" or "start 1,2,3 end" How can I avoide this (undesired) result: paste(s,middle,e,sep=" ") Thank you! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com

...It runs without warnings and generates counts for each factor level AS WELL AS the NAs. Makes sense. Now, I don't want the NAs to be counted. So, I run: ggplot(data = md, mapping = aes(x = a)) + geom_bar(na.rm = T) But I still have NAs in the picture. Why? What am I missing?

Hello! I have a list of variable length. One example is: X=vector("list",3) X[[1]]=1:2 X[[2]]=1:2 X[[3]]=1:2 How could I run expand.grid on the elements of X so that the results would be the same as expand.grid(1:2,1:2,1:2)? Thank you!

...]<-c (X) How can I most effectively transform X into a data frame with columns a, b, and c? I would love to find a generic solution, and not a specific solution like this one: frame<-rbind(X[[1]],X[[2]],X[[3]]) ...because in reality I have a lot of elements of X.

Hello! I wrote a function that returns a data frame. Nowhere in the function do I say print(my.data.frame), but when I run the function - the data frame is printed on the console. Is there any way to suppress it? Thank you! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com

I am not sure if this question has been asked before - but is there a procedure in R (in lm or glm?) that is equivalent to ENTER and REMOVE regression commands in SPSS? Thanks a lot! -- Dimitri Liakhovitski Ninah.com Dimitri.Liakhovitski at ninah.com

...a.frame(x=c("aa.bb","cc.dd.ee")) x$x<-as.character(x$x) x I am sorry for such a simple question - but how can I replace all periods in x$x with spaces? sub('.', ' ', x$x) - removes all letters to the left of each period...
