similar to: Writing a function

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])} }

Thank you very much It works perfectly well Have a wonderful day |---------+----------------------------> | | ripley at stats.ox.a| | | c.uk | | | | | | 04/28/03 12:58 PM| | | | |---------+---------------------------->

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

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 ?

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 2 questions: 1) I'd like to know how to clean the title, the sub title or the labels of a graph. I know how to redefine it with the function title() but it overwrites the previous title and do not replace it 2) How could I clear a whole plot (for example in a multiple figure environment) thanks for your help vincent

Hi R lovers! I'd like to know how to use the parameter 'start' in the function fitdistr() obviously I have to provide the initial value of the parameter to optimize except in the case of a certain set of given distribution Indeed according to the help file for fitdistr " For the following named distributions, reasonable starting values will be computed if `start'

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

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

I need informations about the clara routine. The on-line doc say that the argument stand is a logical, indicating if the measurements in x are standardized before calculating the dissimilarities. Measurements are standardized for each variable (column), by subtracting the variable's mean value and dividing by the variable's mean absolute deviation. If we note STAND = TRUE, I suppose that

Hello, I'm using VAR models in R in order to obtain impulse responses of stock market shock on US economy. I have series of quarterly changes in real gdp, S&P 500 and quarterly level of unemployment for 1985 - 2012 period. My series are stationary. So I did all the steps below. However I don't understand what do irf function results mean. These are the cumulative orthogonal responses

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
