Hello everybody, I want to use the nnet library and my problem is that the algorithm seems to accept only class as target when the neural is fiiting. So the output when I use predict.nnet is also a class. Is it possible to have numeric variable as target ? If yes, what is the syntax ? Thank you. Cordialement, R?gis CHARIGNON

Greetings, Experimenting with the cluster package, and am starting to scratch my head in regards to the *best* way to standardize my data. Both functions can pre-standardize columns in a dataframe. according to the manual: Measurements are standardized for each variable (column), by subtracting the variable's mean value and dividing by the variable's mean absolute deviation. This

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 All , Since dissimilarity is one of quality measures in clustering , I'm trying to access to the sum of dissimilarity as a whole measure. But after running my data using CLARA I obtain : 1128 dissimilarities, summarized : Min. 1st Qu. Median Mean 3rd Qu. Max. 0.033155 0.934630 2.257000 2.941600 4.876600 8.943700 But I can not find the sum of dissimilarity.How can i

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! 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. Let's say I have a matrix, a data.frame or a list that I would like to export as a flat text file that is immediatly transcripted into a table into latex Is there a macro or package that could

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

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

Hi R lovers Obviously I cannot use the underscore "_ " character to name an object in R Is there a special reason for that ? I want to use it to rename a function maybe the problem is due to the nature of the object I work on thanks for any comments on that very little and not very bothering trouble ************************************************************************* Ce

Hi dear sirs, I am wondering why the fit of the time serie x with an arima and the fit of diff(x) with an arma (same coeff p & d) differ one from another here are the output of R: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% > modelarma<-arma(diff(x),c(7,5)) > modelarma Call: arma(x = diff(x), order = c(7, 5)) Coefficient(s): ar1 ar2 ar3 ar4 ar5 ar6 ar7 ma1 ma2 0.06078

Dear R-users, i have two questions : 1- first of all, i wish to know the way to obtain a serie with a format like "00" : ( "01","02","03","04"....) or like postal code ("01100","02222"). for instance, i do : > format(strptime(as.character(c(1:4)),"%H"),"%H") but it sounds complicate and not really

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])} }
