...xts object with the correct time index. However, all of my numerical values are now strings. b <- as.xts(a[,2:dim(a)[2]], order.by=as.POSIXct(strptime(paste(a$Date), '%m/%d/%Y'))) My guess is that somewhere in the large data frame there are a few strings hiding that is causing the who thong to be converted to string.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello, I read and find a way (well, there seems to be several equal implementations) to collect the ssh keys of machines. However they all give only the choice to choose between the key formats. But is there a way to collect both keys of a machine, the rsa _and_ the dss key (and maybe the rsa1 too)? I didn''t find a way to solve this as

I am running Xen 4 and want users to be able to install arbitrary HVM images. We want both PV and emulated drivers to appear. The reason for this is for compatibility with images that were prepared for Xen 3.3, which assume emulated devices exist at boot time (particularly for running the boot loader). If I do not specify on the boot line xen_emul_unplug=never, then under some guest OS''s

Run this code tree<-graph_from_literal(1-+2:3,3-+5,1-+4); graph.bfs(tree,root=1, neimode="out",father=TRUE,order=TRUE,unreachable = FALSE) I do not understand why the father values will give NA 1 1 3 1 rather than NA 1 1 1 3 The reason I am doing this is to obtain the values(by vertex names) or some index of each individual branch in tree.
