Hello Chris,  I 've found two other issues  with MAE and CRPS, giving warning  when running examples. I've the same issue on my data.  Hope that you could find some time to take a look here. Thank you Anna > library(ensembleBMA) Loading required package: chron > example(MAE) MAE>   data(ensBMAtest) MAE>   ensMemNames <-

Hi all, I am wondering if do exist a function in R that allow me to sample or choose randomly the rows (i.e., samples) inside a given matrix. Thank you very much in advance. Cheers, -- Gian [[alternative HTML version deleted]]

With the following code : I would like to plot 4 points, and have the circle and diamond shapes filled with grey. What am I missing ?

Hello I have a list of POSIXct objects, from which I want to extract those values that match a specific date, keeping them in POSIXct format. For a specific date there is 0-2 matching values. As an example (the actual list and objects are much longer): x<-list() x[["first"]]<-as.POSIXct(c("2011-08-27 10:45:00 GMT", "2011-10-30 15:45:00 GMT",

Hello R community, I have a question regarding correlation and regression analysis. I have two variables, x and y. Both have a standard deviation of 1; thus, correlation and slope from the linear regression (which also must have an intercept of zero) are equal. I want to probe two particular questions: 1) Is the slope significantly different from zero? This should be easy with the lm

Hi again, the previous answers were great. I was able to do what was planned. Now, I would like to do the following to a matrix: || year | event | team | total || where I can have multiple "event" per "team", but each "team" only has a "year" and a "total". Thus, this table has multiple lines for the same "team" where only the

Hi everyone: This may be trivial but I just have not been able to figure it out. Imagine the following dataframe: a b c d TRUE TRUE TRUE TRUE FALSE FALSE FALSE TRUE FALSE TRUE FALSE FALSE I would like to create a new dataframe, in which TRUE gets 0 but if false then add 1 to the cell to the left. So the results for the example above should be something like: a b c

dear useRs, i have a list containing 16 matrices. i want to calculate the column mean of each of them. i tried >sr <- lapply(s,function(x) colMeans(x, na.rm=TRUE)) but i am getting the following error >Error in colMeans(x, na.rm = TRUE) : 'x' must be numeric can it be done in any other way? and why i am getting this error?? thanks in advance.. elisa [[alternative

Hello R community, I am trying to combine two CSV files that look like this: File A Row_ID_CR, Data1, Data2, Data3 1, aa, bb, cc 2, dd, ee, ff File B Row_ID_N, Src_Row_ID, DataN1 1a, 1, This is comment 1 2a, 1, This is comment 2 3a,

Dear all, I have a dataset representing several geographical points (locations), each one having a specific value after performing a PCA. Now I'm trying to understand how to separately represent on a geographic map (of Europe) the pattern of PC1,2, ecc.with colors (e.g.heatmap) I have to add that the dataset includes relatively few points. Therefore, I would also like to interpolate the values

Hello, I have a matrix with the distances among sites. And I have another matrix with the presence and absence of each species in each site. I would like to test the spatial autocorrelation among sites. I have tried to use the function gearymoran of the ade4 package, but error messages keep popping up. Do you know any function for me to test the spatial autocorrelation of my data? Thanks,

Hi, I am writing this in a wrong way, can someone please correct me? > A <- matrix() > length(A) <- 6 > dim(A) <- c(3,2) > colnames(A) <- c("X","Y") > A X Y [1,] NA NA [2,] NA NA [3,] NA NA > A$X Error in A$X : $ operator is invalid for atomic vectors > Thanks, cruz

Hi, I am very new to R and wanted to know if there is a package that, given very long nucleotide sequences, searches and identifies short (7-10nt) motifs.. I would like to look for enrichment of certain motifs in genomic sequences. I tried using MEME (not an R package, I know), but the online version only allows sequences up to MAX 60000 nucleotides, and that's too short for my needs..

Hi Everyone, I was hoping someone could help me with the settings for Tinn-R. I see in the screen shots that it has syntax help, or something similar (tips on what functions, etc). I can not seem to get this to turn on in the program, and I am wondering if I have to set up a few options. I quickly read through the help and could not figure it out. Many thanks! - Brock P.S. It appears as
