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

Hi I know that it is very easy to import data from a dbf file to R, by saving the data as csv, for instance. However, I have several hundreds of files to do that. So, I thought of using RODBC to read the dbf files and save it as data.frame. However, I cannot even start (this is my first time using such package): > library(RODBC) > bdades <- odbcConnect("prova.DBF") Warning

I didn't manage to build a c shared library under Windows. I used rcmd shlib both with a source file and with an object file, but I got error messages in both cases.

Dear collegues, How can I get the name of a variable (and not the variable) within a function ? For instance, in the following function, I'd like to create a variable in the dataframe df with the same name to the variable passed in var: prova <- function( var ) { df <- as.data.frame(matrix(nr=20,nc=0)) df[["here"]] <- seq(min(var), max(var), le= 20) # df } for

Dear useRs! I would like to generate a list of all possible (unique) partitions of N units into k classes. For example, all possible partitions of 4 units into 2 classes are (I hope I have not missed anyone): 1,1,1,2 (this can be read as {1,2,3},{4}) 1,1,2,1 1,2,1,1 2,1,1,1 1,1,2,2 1,2,1,2 1,2,2,1 The partitions 1,1,2,2 and 2,2,1,1 are the same and are therefore not two unique
