Hello, I am trying to create a panel with the attached data frame. using the following code: > PanelRio = DataRiopaila[which(duplicated(DataRiopaila$SEC_STE)==T),] > PanelRio=plm.data(PanelRio,index=c("SEC_STE","FechaSiembra")) series Pluv3Meses,PluvMes4al10,Pluv2UltimosMeses,Rad3Meses,RadMes4al10,Rad2UltimosMeses are NA and have been removed It tells me it removes

Dear R users, Let's say I have a list with components being 'm' matrices (as exemplified in the "mylist" object below). Now, I'd like to subset this list based on an index vector, which will partition each matrix 'm' in 2 sub-matrices. My questions are: 1. Is there an elegant way to have the results shown in mylist2 for an arbitrary number of matrices in mylist?

Hello I am trying to import the attached file Curva LIBOR to R.

|Hello, Given a function with several arguments, I would like to perform an lapply (or equivalent) while holding one or more arguments fixed to some common value, and I would like to do it in as elegant a fashion as possible, without resorting to wrapping a separate wrapper for the function if possible. Moreover I would also like it to work in cases where one or more arguments to the original

Hello all, I have been working with b-splines and noted that the splines package is not available in CRAN. Does any body know what happened with it? Or, is there any package that replaces it? Thank you Felipe Parra [[alternative HTML version deleted]]

Dear List, Let's say I have a list whose components are 2 matrices (as exemplified in the "mylist" object below). I'd like to create a list with components being 4 matrices based on an logical index vector. is there a way to simplify what I'm doing to obtain the results in "mylist2"? I'd like something that would work on an arbitrary number of elements in

Hello, I am runnning a program on R with a "big" number of simulations and I am getting the following error: Error: no se puede ubicar un vector de tamaño 443.3 Mb I don't understand why because when I check the memory status in my pc I get the following: > memory.size() [1] 676.3 > memory.size(T) [1] 1124.69 > memory.limit() [1] 4000 which should in theory allow to

hello all, thank you for taking the time I have a matrix A that have column names (let say n columns), I want to reduce the matrix to have just a few of those column (p colums, this is trivial), but for the lines I want only the lines such that A(i,J) is part of a list (J is fixed and known) I am sure it is very easy but I don't find it (I tryed which but it doesn't seem to work) Surely

Hello to all, I have been using an optim with the following call: optim(param_ini,fun_errores2,Precio_mercado=Precio,anos_pagosE2=anos_pagos,control=list(maxit=10000,reltol=1e-16)) depending on the intial values I'm getting the same solution but once I get the convergence message=10 (no convergence) and for the others I get convergence message = 0 Solution1: $par beta1

Hello. I would like to know if there exists in R a function like trunc but where i can choose how many decimal places can I stay with in the number I have (sort of the same as the trunc function in excel). I would like, for example if I have the number 0.974678 and I choose to stay with 3 decimal places to have as ouput 0.974. Thank you Felipe Parra [[alternative HTML version deleted]]

Greetings, I need to compare the ratios of vector sizes like this: length(object1) / length(object2) I have many vector objects to compare, so I would like to do it in a loop. I created a loop like this: mat1 <- matrix() for (i in 1:6) { for (j in 1:6) { mat1[i,j] <- length( paste("object",i,sep="")) /

Hello I am trying to use predict.lm, but I am having trouble getting out of sample predictions. I am getting the same output if I use the following three commands: predict(ModeloLineal,predictors[721:768,]) predict(ModeloLineal,predictors[1:768,]) predict(ModeloLineal) where ModeloLineal is the output from ModeloLineal<-lm(dataTS[,6] ~ predictors[1:720,]), so the first 720 observations of

Hello I am trying to compare a vector with a Matrix's rows.The vector has the same length as the number of columns of the matrix, and I would like to find the row numbers where the matrix's row us the same as the given vector. What I am doing at the moment is using apply as follows: apply(Matrix,1,function(x)all(x%in%LHS)) but this isn't too fast actually. I would like to know if
