Hi, I would like to convert a decimal into a binary number, for instance : 2->(1,0) Any one knows how to do that ? Thanks a lot paul --- [[alternative HTML version deleted]]

Hello, Splus contains the function intbin(x,l). This function allows to make a conversion from an integer x to a binary of length l. for example intbin(3,2) returns 11 intbin(3,3) returns 011 Do you know how to do it in R ? Thank you meriema

Dear listers, I have two questions: (1) Is there a way in R to change the base-n of the calculations. I wnat to run some calculations either in binary (base-2) or base-4. Is there a way to specify that in R - to chnage from the decimal? (2) I also want to extract the digits from a larger number and store them as a vector. I could do it through converting top string, parsing the string and

Hi there, From the vector X of integers, X = c(11999, 122000, 81997) I would like to make these two vectors: Z= c(1999, 2000, 1997) Y =c(1 , 12 , 8) That is, each entry of vector Z receives the four last digits of each entry of X, and Y receives "the rest". Any suggestions? Thanks in advance, Dimitri [[alternative HTML version deleted]]

Dear List, I have a problem I'm finding it difficult to make headway with. Say I have 6 ordered observations, and I want to find all combinations of splitting these 6 ordered observations in g groups, where g = 1, ..., 6. Groups can only be formed by adjacent observations, so observations 1 and 4 can't be in a group on their own, only if 1,2,3&4 are all in the group. For example,
