Dear all, I have an n x n matrix of p-values. The matrix is symmetrical, as it describes the "each against each" p values of correlation coefficients. How can I best correct the p values of the matrix? Notably, the total number of the tests performed is n(n-1)/2, since I do not test the correlation of each variable with itself. That means, I only want to correct one half of the matrix,

Hi Hilmar, weird. The memory problem seems be due to recursion (my R, version 3.3.3, says: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?, just write traceback() to see how it happens), but why does it segfault with xlsx? Nb xlsx is the culprit: neither rJava nor xlsxjars cause the problem. On the other hand, quick googling for r+xlsx+segfault returns tons of

Dear R guru: If I got a variable aaa<- "up.6.11(16)" how can I extract 16 out of the bracket? I could use substr, e.g. substr(aaa, start=1, stop=2) [1] "up" But it needs start and stop, what if my start or stop is not fixed, I just want the number inside the bracket, how can I achieve this? Many thanks yan

Dear All I'm trying to sort a matrix using function order, Some thing really odd: e.g. abc<-cbind(c(1,6,2),c(2,5,3),c(3,2,1))## matrix I want to sort if I do abc[ order(abc[,3]), increasing = TRUE] the result is correct [,1] [,2] [,3] [1,] 2 3 1 [2,] 6 5 2 [3,] 1 2 3 But if I want to sort in decresing order: abc[ order(abc[,3]), decreasing = TRUE] the

Dear All, I'm wondering if there is a R function could give me all the combinations of the grouping/cluster result, given the number of the groups. e.g. 3 objects: x1 x2 x3, number of groups is 2 so the result will be group1:x1,x2; group2: x3 group1: x1;group2: x2,x3 group1: x1,x3;group2: x2 many thanks yan

Hi, this is a problem that occurs in the presence of two libraries (limma, xlsx) and leads to a crash of R. The problematic code is the wrong application of sweep or the product ("*") function on an LIMMA MAList object. To my knowledge, limma does not define a "*" method for MAList objects. If only LIMMA is loaded but not package xlsx, the code does not crash but rather

Dear brainy R users, I need to output a matrix, with two colors , meaning some elements using different color I normally use write.table(table.m, file="table file name.csv", sep=","), how could I pass the index for the color ?

Dear all, I am a happy user of R console, but I would like to see syntax coloring. I use R 2.12 in Ubuntu Linux. I have found the packages "xterm256" and "highlight", but I was not able to figure out how to use it to highlight the syntax in console output. Also, I tried several GUI interfaces, but I was not able to find something that suits me better than the default R

I have a four-digit string I want to convert to five digits. Take the following frame: zip 2108 60321 60321 22030 91910 I need row 1 to read '02108'. This forum directed me to formatC previously (thanks!) That usually works but, for some reason, it's not in this instance. Neither of the syntaxes below change '2108' to '02108.' The values in cand_receipts[,1] are of

Dear All, I'm generating a heatmap, is there a way to make Y axis name display horizontally, X axis name display vertically?

Dear R users, if all my numerical variables in my datasets having the same units, may I leave them unnormalized, just do cv.glmnet directly(cv.glmnet(data,standardize=FALSE))? i know normally if there is a mixture of numerical and categorical , one has to standardize the numerical part before applying cv.glmnet with standardize=fase, but that's due to the different units in the numerical
