similar to: differing behaviour between xts (0.6-7) and zoo (1.5-8)

Hello, I'm a complete newbie to R. Spent this past weekend reading The Art of R Programming, The R Cookbook, the language spec, Wikis and FAQs. I sort-of have my head around R; the dizzying selection of libraries, packages, etc? Not really. I've probably missed or failed to understand something... I have very a simple data set. Two years (ish) of temperature data, collected and

Hi, I have an xts starting with a number of columns (currency pairs see below), then I add new ones which are derived from existing ones (like adding the moving average of a column) by merging the new columns one by one. These get the name of the column they are calculated from concatenated with ".1". All done by merge.xts, easy. Now, I have a function (procState below) which generates

Hello, I have the following loop for two data sets: diveData_2008 and diveData_2009. It uses two other data: diveCond_all and fishTable. The problem is at the point to identify the dive_id for the given index (index is timestamp). It keeps on saying for the1st loop Error in fishReport$dive_id[i] <- dive_id : replacement has length zero for the 2nd loop Error in fishReport$dive_id[i + j] <-

Please don't use lvm thin for vm. In our hosting in Russia we have 100-150 vps on each node with lvm thin pool on ssd and have locks, slowdowns and other bad things because of COW.

Do you have some comparasion of IO performance on thin pool vs. qcow2 file on fs? In my case each VM would have its own thin volume. I just want to overcommit disk-space.

I'm testing out quantstrat using a simple one-indicator strategy. The error I get after applyStrategy(...) is Error in .xts(e, .index(e1), .indexCLASS = indexClass(e1), .indexFORMAT = indexFormat(e1), : index length must match number of observations In addition: Warning messages: 1: In match.names(column, colnames(data)) : all columns not located in roc_15 for STOXX.Open STOXX.High

Hello, as usual, I'm few years behind trends so I have learned about LVM thin volumes recently and I especially like that your volumes can be "sparse" - that you can have 1TB thin volume on 250GB VG/thin pool. Is it somehow possible to use that with libvirt? I have found this post from 2014: https://www.redhat.com/archives/libvirt-users/2014-August/msg00010.html which says

In the past, I've used LVM on MD RAID, and I'd like to try using LVM RAID in order to also add dm-integrity data to some LVs.? I've added new PVs to my VG, and I've converted some of my LVs to raid1 types, but I also have one thin pool that I use for VMs with multiple layers of snapshots.? That pool can't be converted, directly: # lvconvert --type raid1 -m 1

This defines __smp_xxx barriers for powerpc for use by virtualization. smp_xxx barriers are removed as they are defined correctly by asm-generic/barriers.h This reduces the amount of arch-specific boiler-plate code.

Hello, I am a new R -user and request your help for the following problem. I need to merge two dataset of longitudinal study which has two column (id and respose) common. when I used merge option to join the datas side be side, because of the repeated subject id, I got larger data set which is not accurate. I would like to connect twi data sets by id and response in such a way that data are
