Hi everybody, I have the following problem. I have a vector containing character elements, such as: list = c("aa","bb","cc","dd","ee") I want to create an index which identifies the elements that are different from, e.g. "aa" and "bb". When I do the following: jj = list!="aa" & list!="bb" > jj

Dear R helpers, I know R language at a preliminary level. This is my first post to this R forum. I have recently learned the use of function and have been successful in writing few on my own. However I am not able to figure out how to apply the function to multiple sets of data. # MY QUERY Suppose I am having following data.frame df = data.frame(k = c(1:8), ratings = c("A",

Hello, I have the following problem. I am running simulations on possible states of a set of agents (1=employed, 0=unemployed). I store these simulated time series in a matrix like the following, where rows indicates time periods, columns the number of agents (4 agents and 8 periods in this case): Atr=[ 1 1 1 1 1 1 0 1 1 1 0 1 1 1 0 1 0 1 0 1 0

Dear users, I have a weird questions. A friend of mine, some years ago, supposedly trying to access help files without Internet connection, got something like this error message: "The Pythia is not available, please go to Delphi" When I've heard about it, I found it very funny and I'd like to be able to get it. Does anyone of you know how to get this error message again?

Dear All, Sorry for asking a newbie question. I want to ask how to import 1000 datasets whose file names are labelled from data1.dat to data1000.dat into R so that they are named M[1, , ] to M[1000, , ] accordingly. Thank you very much. Best Regards, Ray [[alternative HTML version deleted]]

Hi, I have a data frame with 100 variables (numeric and non numeric types), and I want to join them in only one column, like a vector, but i want to keep the non numeric variables like they are. I know that i can do something like this: Suppose that my data is in df variable new_df<-data.frame(c(df[,1],df[,2],df[,3],df[,4],...........) This works but i have 100 variables! Any way of doing

Given: > filename<-paste(tempdir(),"\\","myfile.txt",sep=""); > sub("\\\\","/",filename); [1] "C:/DOCUME~1\\AJAYAS~1\\LOCALS~1\\Temp\\Rtmp2f270T\\myfile.txt" Note: Only the first occurence of \\ is replaced. What is the syntax for replacing every occurence? Thanks. [[alternative HTML version deleted]]

One column ('Season')contains factor data representing seasons, e.g. spring, summer, autumn and winter. Another column (called 'Day') contains data representing wether the day is a working day (I use 'Wd' for short here)or weekend (I use

Hi, I got a small problem on how to define the vector index without manually inspect the vector. example: y=c(2,3,5,2,4,6,8,3,6,2,5) #I have ten set of this kind of vectors (with different values but same length) that I would also like to run the routine below #say; v=the first index in y where the value is larger than 4, in this case index 3, value 5 #what I would like to do is take y[1:v]

Hi! I would like to post the following question: I was trying to figure out how to do the simulation shown in Fig 10.6 of John Verzani's book 'Using R for Intro Statistics'. It is on page 290, with a description on the previous page. It seems like a simple thing... Just needing to duplicate a procedure. (Perhaps I need to do it with a loop?) This is what I was trying:

Dear R users, I would like to draw map and import it in maptools/spatstat packages. The 'raw data' I have come from a web page (<map>...</map>) and are basically a list of coordinates of a polygon. I would like to know how to import them in R; I checked the maptools packages, but all the examples use existing .dbf files. I just have a (serie of) text file(s) looking like
