Dear list, in the following loop im generating objects of type table. What I would like to do is to put all those objects together in a list (that i called cc).I did this but the result is not what i espect to get: cc=list() d=1 for (i in data) { cc=list(cc,assign(paste("n",d,sep=""),table(i,subsample$vD31NADD))) d=d+1} I know that this won't work properly:

Dear list, I have a question. I have the RKward configuration. I don't know what happened but now when I open R I have in my workspace data frames with which I used in the past sessions.How can I set RKward in order to open a new workspace? Thanks a lot [[alternative HTML version deleted]]

Dear R list I have a problem with NA, which should be a string, but R seems that it doesn't recognize it. What I do is first give the format command to my data frame: format.data.frame(mydata,big.mark=" ") so I give a blank as thousand separator. All my records in my data frame become strings, so instead of having NA I have "NA". I try to convert "NA" in

Dear list, I have a problem with the cumsum function. I have a data frame like the following one variable Year value EC01 2005 5 EC01 2006 10 AAO1 2005 2 AAO1 2006 4 what I would like to obtain is variable Year value cumsum EC01 2005 5 5 EC01

Dear list, I have the following problem, what i'm trying to do is to built a function which does the following calculationg in a recursive way: I have a data frame more or less like this: variable year DELTA EC01 2006 / EC01 2007 10 EC01 2008 5 EC01 2009 9 And then I have at time

Hi, I need to generate the time series of the production, but as I'm new to this topic I am not able to do that. This is what the time series should be: PROD(t)=PROD(t,T) PROD(t-1)=PROD(t-1,T) PROD(t-2)=PROD(t-1)*PROD(t-2,T-1)/PROD(t-1,T-1) PROD(t-3)=PROD(t-2)*PROD(t-3,T-2)/PROD(t-2,T-2) ... ... ... from PROD(t-2)...it will get the same expression; where PROD(t,T) is the value of the

Hi all, I have a question about global and local variables.First of all, a variable defined in a for loop is it a local or global variable?? Second, I'm trying to build a loop in the following way: I have these 3 data frames bilanci_2005<-bilanci1[ANNO==2005,] bilanci_2006<-bilanci1[ANNO==2006,] bilanci_2007 <--bilanci1[ANNO==2007,] LOOP: v=list(2005,2006,2007) for (a in v){

Dear list, I have a question I'm trying to use the following command in R, but it gives me an error message.The command is: data<-ddply(data,c("year","name"), transform, check1=ifelse(check1==1 & check2==1, 1,NULL)) so in my data frame I already have the check1 variable, if the conditions (check1==1 & check2==1) is respected, check has to have 1 as value,

Dear list, I'm using the Sweave function in order to get some report. Here one chunk: <<echo=F,results=tex>>= report<-lapply(repor, function(x) { (print(xtable(data.frame(x[1:2,]), align="|l|rrr|"),floating=FALSE,tabular. environment="longtable",include.colnames=FALSE,size="\\small"))

Dear all, I'm using xtable package in order to produce Latex table. There is a way to specify not only the alignment but also the width of table colums?? Thanks for your attention.

Dear all, I have the following problem. I have a List of time series dataframe.I'm trying to produce specific graph for each element of my list. The code is: This is my list: Lista_import<-lapply(Lista_import, function(x){ x2<-subset(x, select=c("ANNO","DICHIARANTE","PARTNER", "quota")) x2<-cast(x2, ANNO+DICHIARANTE~PARTNER) x2<-

Dear all, I'm having problems with the tick of my graph. I'mpcombining lines and barplot. For my I'm using the function axis combined with the function pretty to have more efficient tick, but all my tick (for example, 300 as my max tick and -100 as my min tick) are not printed on my graph. So I would like to have for the left axis the seq from 0 to 100 (with 0 and 100 printed on
