Hi I am new on this forum. I am searching for a function in R which provides all partitions of a set, say for the set {1,2,3} you get {{1,2,3}} {1,{2,3}} {2,{1,3}} {3,{1,2}} {{1},{2},{3}} . The number of partitions of a set is given by Bellsche`s number. The number of possibilities of length (this is the number of subsets included in the partition) of the partition is given by the partition

Hello everyone, I am trying to estimate the parameter b. I have Y and X1 which I know and they are both random. However, I also have X2 which I don't know and is also random. I want to estimat b from the model: Y = b*X1 + ( 1 - b ) * X2 Can anyone offer some suggestions. The values of Y and X1 are both pvalues so they are constrained in (0,1). -- Thanks, Jim.

Hi folks, I'm stuck with a problem that I suspect has a trivial solution... I have a function, call it foo, that takes a number of arguments which it uses as parameters for a simulation. For later analysis, foo stores the names of the objects passed to it along with the simulation results in its output (written to a database). The objects names are accessed with deparse(substitute(argname)).

Hello, I have a nested named list structure, like the following: x <- list( list( list(df1,df2) list(df3, list(df4,df5)) list(df6,df7))) with df1...d7 as data frames. Every data frame is named. Is there a way to get a specific named element in x? so, for example, x[[c("df5")]] gives me the data frame 5? Thank you in advance! Best, Friedericksen

Hi All, I want to have an array/ matrix that looks this x<- 0 0 1 1 1 3 5 4 4 7 -1 8 9 10 6 I hope this makes sense. So basically if I want x[1,3] it will access 0 and similarly x[4,2], -1.
