constraint matrices in vglm (VGAM package)
Hello R users, I am performing a multinomial logit regression and would like to constrain a few model coefficients to be equal. Here is my model: multi <- vglm(case123con ~ SNP_A1+SNP_A2+age, multinomial, work.analy) where case123con is a four level categorical variable (case 1, case 2, case 3, control) and SNP_A1 and SNP_A2 are indicator functions (yes/no). The output of this

Multiple allowed signer files in `ssh-keygen -Y verify`
Hello, I'm currently evaluating using `ssh-keygen -Y verify` to check OS artifacts (e.g. packages) and I noticed that the `-f allowed_signers_file` option can be passed only once. A side remark: technically it can be passed multiple times without a warning but the last invocation overrides all previous ones. Tested using: $ ssh-keygen -Y verify -f allowed_signers -f /dev/null -n file -s

Hello, I'm looking for help on the best approach to get "multi-value" data fields into R for simple descriptive analysis. ------------------------------------- I am new to this list and new to R, but I really want to get over the hump and get productive with it. Some help with how to best get the following data into R would be greatly appreciated. I have programming experience
