Hi, I had the following code: testp <- rcorr(t(datcm1),type = "pearson") mat1 <- testp[[1]][,] > 0.6 mat2 <- testp[[3]][,] < 0.05 mat3 <- mat1 + mat2 The resulting mat3 (smaller version) matrix looks like: NA 0 0 0 0 NA 0 NA 0 0 NA 2 0 0 2 NA To get to the number of times a '2' appears in the rows, I was

Hi , Is there any C API to the R API nrow of dataframe ? x<- data.frame() n<- nrow(x) print(n) 0 Example : My C function which deals with data frame looks like and I don't to send the number of rows of data frame .I want to detect it from the function itself, my function take data frame as argument and do some on it. I want API equivalent to nrow. I tried Rf_nrows,Rf_ncols . No

...3.4.0 because gcc complains that "ebp" cannot be used as a constraint. If preserving ebp is necessary then it will have to be done in the assembler code. Gcc 3.3.3 just seems to ignore the constraint. It didn't do anything special to preserve the register. I also noticed that getnumrows returns the contents of 0x484 which is the number of rows minus one but menu.c has this ms->numcols = getnumcols(); ms->numrows = getnumrows(); ms->maxcol = ms->numcols - 1; ms->maxrow = ms->numrows - 1; which makes maxrow = rows - 2. Is this intentional? BTW, if...

Dear all, We are trying to clean multiple realizations of a pattern. Erroneous NODATA and spurious DATA occur in the realizations. As we have to do a 1000 realizations for many patterns, efficiency of the code is important. We need to correct the realizations with a 'mask' pattern of DATA/NODATA. We think an ifelse should do the job. Spurious DATA will be simply removed using the

I have a dataframe of 25 columns and 100,000 rows called ?testdf?. I wish to build a new dataframe, with 14 columns and 100,000 rows. I wish the new dataframe to have the ?trailing 12 column? mean. That is, I want column 1 of the new dataframe to have soemthing like: ?( mean(testdf[,1:12],na.rm=T)? What is the best way to accomplish this?

Hey Murali, While playing with HDT which uses your menu, I found I can't reach more than 24 rows whereas my screen is 25. set_windows_size() relies on getnumrows() to define the maximum number of possible rows. But regarding to getnumrows() code, it sounds to report "// Actually numrows - 1". On my screen which is 80x25, getnumcols x getrowcols reports 80x24. The set_windows_size() is so refusing to set the screen up to 80x25. Is it a desired...

Hi, I?m new to R but I?m interested in using the fdim package to find the fractal dimension of a dataset. I downloaded the the package from https://cran.r-project.org/src/contrib/Archive/fdim/ and successfully installed it together with xgobi. However, when I try to run the first example, after df <- fdim(mydata,q=0,Alpha=0.3) I get the following error: Error in .C("pointdif",

Hm, I am not an expert in this field but trying to use obviously old package which was removed about 5 years ago from CRAN is asking for problems. There is probably some incompatibility between recent R version and obsolete package. You either 1. need to install/compile R version from 2012 and install/compile this old package for this version. 2. Or you could try to find some similar

...rixes as long as possible and not the its (S4) objects, since this makes some commands very slow (like union). There are also other packages like zoo, tsseries (I guess) and certainly Rmetrics, which should have all you need Most functions transform directely and easily. Among others, I missed the numRows() and numCols() etc in R, but this can be redone quickly. One big advantage of S-Plus is the possibility to edit graphics and to make Powerpoints presentations very quickly. Also the Excel interface is already build in. In R you must always programm to whole picture, which is ok if you are doing...
