[R] Mailing List

Dear All, I am using R to do my work and thank you very much for developing, maintaining and making such excellent software available to anyone that is interested enough to ask for it. I have registered at Nabble. I was wondering the right forum for me to send my help request. I have tried

Re: [R] Data reshaping with conditions

Hi sri, I think that I see what you mean. Your statements: x = Count_A_less_than_max of (Count type B) y = Count_A_higher_than_max of (Count type B). I took to mean that you wanted a logical value for x and y. Looking more closely at your initial message, I see that you wanted _all_ values of A

It sounds like you want to use grid.arrange() from gridExtra: https://cran.r-project.org/web/packages/gridExtra/vignettes/arrangeGrob.html Hope this helps, Ulrik On Thu, 21 Apr 2016 at 00:52 Jeff Newmiller wrote: > >

Thanks for the response. Yes, in that situation a solution of x = 1 would be just as good as x = 1000 or any other value of x for me (but in my problem the matrix has nonzero rank, so I can't just randomly choose a vector and have it be a solution). If it helps, what I'm interested in is the R

This is not a solution but your lsfit attempt #Error in lsfit(A, b) : only 3 cases, but 4 variables lsfit(A,b) gave that error because lsfit adds a column of 1 to its first argument unless you use intercept=FALSE. Then it will give you an answer (but I think it converts your sparse matrix
