similar to: data.table is on CRAN (enhanced data.frame for time series joins and more)

I've two data.tables as shown below: *** N = 10 A.DT <- data.table(a1 = c(rnorm(N,0,1)), a2 = NA)) B.DT <- data.table(b1 = c(rnorm(N,0,1)), b2 = 1:N) setkey(A.DT,a1) setkey(B.DT,b1) *** I tried to change my previous data.frame implementation to a data.table implementation by changing the for-loop as shown below: *** for (i in 1:nrow(B.DT)) { for (j in nrow(A.DT):1) { if

Hi all, Say if I have a data table which consists of 4 column: itemID, location and price, which location is a text field and itemID and location together forms the primary keys. when I tried to run setkey (DT, itemID, location), I got the following message: Error in setkey (DT, itemID, location) : All keyed columns must be storage mode integer Is there any way I could define a non-numerical

Given that the xenvm machine is based on vexpress but with an extremely limited selection of peripherals (the guest is supposed to use virtual devices instead), add "xen,xenvm" to the list of compatible machines in mach-vexpress. Changes in v2: - remove include skeleton; - use #address-cells = <2> and #size-cells = <2>; - remove the debug bootargs; - use memory@80000000
