...can't quite see how to do it without manually sub-setting the parent data frame and then putting it back together again. Anyone able to get me started on a cleaner (more R-like) approach?

Dear R-devel mailing list, I am wondering whether the "theta" and "phi" parameters of the "persp" function in the graphics commands are named in error (the names seem to have been swapped). Also, in the documentation to "persp", reference is made to "colatitude" when the effect in the image is actually that of "latitude". Thank you,

Hi, I created a function for obtaining the normal cumulative distribution (I know all this already exists in R, I just wanted to verify my understanding of it). below is the code I came up with. cdf<-function(x) { erf<-function(x) { # approximation to the error function (erf) of the # normal cumulative distribution function # from Winitzki

Dear R-helpers, In my dataset I have two continuous variable (A and B) and one factor. I'm investigating the regression between the two variables usign the command lm(A ~ B, ...) but now I want to know the regression coefficient (r2) of A vs. B for every factors. I know that I can obtain this information with excel, but the factor have 68 levels...maybe [r] have a useful command. Thanks,

Hi everyone, i am trying to group close numbers in a vector. For example i have a vector x = [1 2 4 7 9 10 15]. I want the code to pick 1 2 4 (max difference between successive numbers is 2) and assign them to variable a, then pick 7 9 10 and assign them to b and 15 to c. But since i do not know how many groups there will be the code should create a,b,c etc as it goes along. So if x = [1 2 4 7 9

Dear Sir, I am writing to inquire about normality test given in nortest package. I have a random data set consisting of 300 samples. I am curious about which normality test in R would give me precise measurement, whether data sample is following normal distribution. As p value in each test is different in each test, if you could help me identifying a suitable test in R for this medium size of

Hi all, I attach a picture, with my output plot. I put this command to obtain it: hist(MCT[,2],probability=TRUE,xlab=" ",ylab="Max",main="M distribution") lines(density(MCT[,2]), lwd = 2) The problem is that when I extract the "bell" is too high? And the higher part doesn?t appear in the plot. There is some trick to adjust the line on the plotted area?
