> d <- data.frame(id=1:4, no.contacts=c(2,3,3,1)) > d$contacts_list <- list(3:4, c(1,3,4), c(4,2,1), 1 ) If you store that information in a longer format, with each row being an edge to the relationship graph, it can make further processing easier: d2 <- with(d, data.frame(id=rep(id, vappl

Re: [R] variable length lisin in data frame

Hi, Try:  dat <- data.frame(id=1:4, contacts_list=I(list(3:4,c(1,3,4), c(4,2,1), 1)), `number of contacts`=c(2,3,3,1),check.names=FALSE) attr(dat$contacts_list,"class") <- NULL #if needed  dat A.K. Dear Group, I have data like the following id   contacts_list   number of contacts

If you are using the nnet package, the caret package has a variable importance method based on Gevrey, M., Dimopoulos, I., & Lek, S. (2003).

[R] Variable importance - ANN

Hi everybody, I created a neural network for a regression analysis with package ANN, but now I need to know which is the significance of each predictor variable in explaining the dependent variable. I thought to analyze the weight, but I don't know how to do it. Thanks in advance, Giulia Di Lauro.

Re: [R] variable standardization in manova() call

thank you for your reply. However, your remark was not so clear to me so I attach a short script I tried to launch. The comparison between results got from MANOVA() call with the non-standardized and standardized version of the same data frame, convinced me that it is not necessary to standardize
