Hello, altough I'm not an expert, I found a solution (maybe not the most elegant.....)
d<-as.Date(c("2000/01/03","2000/01/05","2000/01/19","2000/01/28")) r<-rnorm(4) da<-data.frame(d,r) a<-as.Date("01/01/2000","%d/%m/%Y") b<-as.Date("30/01/2000","%d/%m/%Y") ab<-seq(a,b,by=1) c<-format(ab,"%a") date<-data.frame(ab,c) date<-subset(date,c!="Sun") date<-subset(date,c!="Sat") names(da) <- c("a","r") names(date) <- c("a","day") outp <- merge(date,da,all=T) outp$hd <-0 outp$hd[!is.na(outp$r)] <- 1 Kind regards Bart saikat sarkar wrote: > > Hi, > > R experts.
