Hi R lovers! I'd like to know the trick to get a plot with a title associating variable and text I'd like to plot something like for (i in 1:10) plot(x[,i],ylab="Serie" & i) to get Serie 1 Serie 2 so on and so forth... of course it doesn't work. If somebody could give me an idea, it would be very nice thank you very much and long life to R Vincent

Dear sirs, I would like to know if there is a function to compute the pvalue for the significancy of arima coef in an arima object created by the arima function. I have written this one: pvalueArima<-function(x,arima) { t<-(arima$coef)/(diag(arima$var.coef)^0.5) df<-length(x)-length(arima$coef) 1-pt(t,df) } Has somebody already implemented something equivalent ? thank you for your

Hi R lovers! I am a beginner in coding with R so my question may be very easily solved but I don't know how. I have written the following function in a .txt file ClearDelta <- function(Matrix) { ncol<-ncol(Matrix);nrow<-nrow(Matrix); for (i in 1:nrow) { for (j in 1:(ncol-1)) {if (Matrix[i,j]==NA) (NA->Matrix[i,j+1])} }

Hi R lovers! I have discovered recently that graph can be exported from R in a Latex compatible file thanks to the pictex command I would like to know if there is the equivalent while exporting datas.

Hi r lovers! I 'd like to apply the cor() function to a matrix which have some missing values As a matter of fact and quite logically indeed it doesn't work Is there a trick to replace the missing value by the mean of each variable or by any other relevant figures ? Or should I apply a special derivate of the cor() function, (I don't have any idea if it exists and have some trouble to

Hi R lovers! Are there any means to define and plot a function given the equation that specifies the function? For example I'd like to plot and work with the Gumbel Distribution density defined by Lambda(x)=exp(-exp(-x)) My question may appear very simple but I haven't got an idea yet about how to do that. I could plot something with x a vector/set of value but I don't know how to

Hi r lovers, I have written the following function > ClearDeltaBis function(Matrix){ for (i in 1:3) { for (j in 1:2) {if (is.na(Matrix[i,j])) NA->(Matrix[i,j+1])} } Matrix } it looks correct but when I try to implement it on the MatCor Matrix I get this error message >

Hello R lovers I have written a little cute function to count the number of missing value per row in a matrix and return the percentage of missing value it takes a lot of time to run with a 1000 rows matrix I'd like to know if there is a function already implemented to count the number of occurence of a given values in a vector For information, here is the function count<-0 for (i in
