[Rd] Manipulating R lists in C

Hi, I have been studying the R manual on lists but cannot seem to create a simple R list in C - I keep on getting "'dimnames' applied to non-array" whenever I attempt to assign names to the list elements: Wanted output a list structure something like [ type="Bid", price=2.0, volume=10

[Rd] Data table in C

After getting one list done, I am now struggling to form a data frame in C. I tried to do a list of lists which gives me : $ $[[1]] [1] "BID" $[[2]] [1] 0.6718 $[[3]] [1] 3e+06 $ $[[1]] [1] "BID" $[[2]] [1] 0.6717 $[[3]] [1] 5e+06 $ $[[1]] [1] "BID" $[[2]] [1] 0.6717 $[[3]] [1] 1720

[Rd] setIs() and setAs()

Dear R-devel, If we have two classes that have the same representation but with slightly different constraints, say something like: setClass("foo", representation=c(a="numeric", b="data.frame")) setClass("bar", contains="foo", validity=function(object) if (length([EMAIL PROTECTED]) < 2)

[Rd] setting up a plot without plotting any data

Someones you need to set up a plot before the data is ready to plot. You know the desired axis limits (xlim and ylim), but don't have the data all in one vector. You would like to set up the coordinate system, perhaps draw the axes and titles, but draw no points. You can do that with plot(x=x

Re: [Rd] Data table in C

Data frames are column, not row oriented so you actually want your list-o-lists to be $type [1] "BID" "BID" "BID" $price [1] 0.6178 0.6717 0.6717 $volume [1] 3e+06 3e+06 1720 so you'd create a VECSXP of length 3 and then three data vectors (also of length 3 in this case). One STRSXP and two
