Hello everybody, a question that connect to the question of Frederik Karlsons about 'how to stand. betas' With the stand. betas i can compare the influence of the different explaning variables. What do i with the betas of factors? I can't use the solution of JohnFox, because there is no sd of an factor. How can i compare the influence of the factor with the influence of the numeric

Hi all This seems like a very easy question, but I have not found a simple answer to it: If you have a dataframe, how to you plot two of then in different colors depending on a third variable?

Dear R-users I have some doubts about with converting dates... e.g. dates data 23/12/1975 0.8678 03/01/1976 0.8736 28/01/1976 0.765 13/03/1976 0,9654 ... I think that converting these dates can easily my plots... is there a R function to convert these dates to a julian dates and so plot that variables?? The help files as.POSIXlt, POSIXt and others don't aswer my doubts...

Hello! I use the version 1.4.0 for Windows. I have made boxplots but only half of the symbols (three letters each) show up on the X-axis? How t can one change their size or orientation so that all show up? I attach the pdf file to illustrate better the problem.

Hello, I'm just start learning R/S-Plus, so I think this 2 doubts is going to be too easy for you... 1) I couldn't discover what is the command for a concatenation of 2 variable strings. 2) For example, if I have three variable strings, and each one has the name of a variable in a data matrix: a<-V1 b<-V2 c<-V3 , is it possible to construct a command like this:

Hi, Is it possible to add a subtitle that appears directly below the main title? I tried the "sub" parameter, but it adds sub-title to the bottom of the plot.

Hi, I am using the scan function to read from a file. In general the syntax I am using is as follows: scan("myfile", list(a = "", b="", c="", d=""), sep=",") The file I am trying to read contains a #< in the 'd' field. When the file is read into an object, the d field comes as "" for that particular string. I

Hi! I want to display 2 graphs with different number of data points on the x-axis. The code below scales them so it seems that testtwo has the same number of data points as testone. How can I fix that? thanks. z<-1:50; x<-1:100; plot(x,testone,type="l",xlab="",ylab="",main="",lty=4,axes=FALSE,ylim=c(-1.0,1.0),cex=1); par(new=TRUE);

Dear Sir, I have been working with R for some time now and I am very happy with it, but I have found a problem that I could not resolve. Could you please give me some hint about how to transform POSIX time data in seconds to string format?. (eg. 995752800 -> year-month,day,hour,min, sec) I tryed with Sys.time(), strptime() and date() but without success. Thank you very much in advance

Hello everybody! Spse I have the following X <- seq(1:100) #(a dim(100) sequence of integers 1:100 representing the possible actions of player 1 and player2 in a game) BR2X<- br2(X) #(a dim(100) sequence of points on range (1,100) representing the best response function of player 2 to player 1:s actions) BR1X<- br1(X) #(a dim(100) sequence of points on range (1,100)

I'm trying to duplicate some graphs from powerpoint in R package. One of things I'm having trouble with is I don't understand how to use the points command to create different sets of points with different color and marking attributes, and a legend on the graph. Where should I look? I can't seem to find an example of two different sets of data on the same graph.

I am new on R, so I have a maybe naive question: if I have many large data.frames and I use only one or two per session, what's the best way? If all are stored in the actual .Rdata, the system gets slow. On the other hand, I wouldn't like to make a separate package for the data. Should I save it with save() and then remove it with rm() ? Could I reload it then? Thanks for suggestions

Hi group, To mention it in advance, I am an R newbie, and most likely, my question is more a mix of smaller, simpler tasks. Anyway, I got mixed up between by, select, aggregate, lapply etc. My problem is as follows : I have read data in and transformed them into a matrix for no special reason so far. This matrix contains a column with regard to which I would like to group, i.e. one realisation
