Hi, I am working on a dataset in which a number of venture capitalists invest in a number of firms. What I am creating is an asymmetric matrix M in which m(ij) is the volume (sum) of coinvestments of VC i with VC j (i.e., how much has VC i invested in companies that VC j also has investments in). The output should look like the "coinvestments" matrix produced with the code below. If

I can put all sorts of traps in the script itself, but when called from the command line the r window simply flashes and closes. There's probably a way to find out why rscript is failing, but I don't know it and can't seem to find it

Dear R-users, How do I obtain a sequence of dates consisting of only weekdays without the weekends in R? In S, I can do the following: timeSeq(from="12/17/2007", to="8/25/2008", by="weekdays") I tried using looking at timeSequence (fSeries package) and seq.Date (base package) but I do not know if I can specify "weekdays" rather than "day".

Hi all, Diverging from my research based number crunching I am interested to see what, if any R packages are out there that can access daily market values of investment funds (e.g. using http://quote.morningstar.com/fund/f.aspx?t=PDMIX) then store the data value (i.e. NAV =$11.56 ) with date retrieved so these can be plotted with ggplot2 on some regular basis.
