Hi all. I've been lurking and posting on this list for a few years now. Prior to that, I managed the US Convertible Arbitrage portfolio for Amaranth Advisors. I recently agreed to manage a similar portfolio for a different hedge fund and am looking for someone to join me, essentially as the principal quant for a new San Francisco office. I've been very impressed with the posters on

Dear Katherine, For your first question: If you are creating these files in a specific folder, then list.files() #[1] "Individual_Present_Value_BONDS.csv"? "Individual_Present_Value_Equity.csv" #[3] "Individual_Present_Value_FOREX.csv" gives you which files are present.? But, suppose you have other files too in the folder and you want to check only the above

I have continous oom&panic situation unresolved. I am not sure system fills up all the ram (36GB). Why this system triggered this oom situation? Is it about some other memory? highmem? lowmem? stack size?

Dear group, I know this issue has been already covered, and before you reply I must say I have read the R-FAQ and search the mailing list archive. I still can't manage to change my factor to numeric as I couldn't find any clear answer. Here is my df : Pose1 <- structure(list(DESCRIPTION = structure(c(1L, 2L, 3L, 4L, 5L, 8L), .Label = c(" SUGAR NO.11 May/10 ", "COTTON

Found this solution. It is maybe not the most elegant way, but it does the job. > a=as.data.frame(substr(lme$DESCRIPTION,1,14)) > colnames(a)=c("DESCRIPTION") > lme=as.data.frame(c(a,lme[,2:3])) > lme DESCRIPTION CLOSING.PRICE POSITION 1 PRIMARY NICKEL 25,755.7100 0 2 PRIMARY NICKEL 25,760.8600 0 3 PRM HGH GD ALU 2,415.9000 0
