Hi All! I'm trying to convert serial numbers in Excel to dates in R. For each single "thedate" entry, I get a correct answer. But if I try using the for loop, I get bizarre numbers in "mynewdata". thedate<-as.matrix(40548:40759,ncol=1) exdate<-function(){ mynewdate<-NULL for(i in 1:nrow(thedate)){ mynewdate[i]<-as.Date(thedate[i,1],origin="1899-12-30") } print(mynewdate) } exdate() Thank you very much!

I have a data.frame that was built from a number of smaller data.frames with rbind. Each ssmaller data.frame bound together runs over the same date ranges. The format of the whole thing looks like this: Trade PosType EnDate EnTime ExDate ExTime PL_Pos 1 1 1 1040107 915 1040107 1300 164 2 2 1 1040108 909 1040108 1300 184 3 3 1 1040115 921 1040115 1300 64 4 4 1 1040120 1134 1040120 1300 124 5 5 1 1040121 923 1040121 1300 84 6...

...A simple simulated example is given below. Two things are happening in the analysis that I do not understand: First, although all the data have x1>=x2, plot returns a plot with estimates for all values of (x1,x2), including where x1<x2 and therefore there are no data. I have tried using the exdat option to specify that the predictions should be carried out only on the existing data, but this does not seem to work. (See example below.) How can I tell plot / npplot to plot only within the range of the data? Alternatively, can I specify the exact set of points at which the plotting should occ...
