While debugging a bootstrap problem, I noticed that SmallVector stores one element in SmallVectorImpl and N - 1 in SmallVector. It also assumes that all elements are continuous in memory. Does C++ makes any guaranties about the relative memory position of a base and parent classes? I haven't studied it a lot, maybe we can keep N elements in SmallVector and pass the pointer to SmallVectorImpl

Let's say I have a data.frame like A B C TS other columns 1 1 1 12345 1 1 1 56789 1 2 1 23456 1 2 2 23457 2 4 7 23458 2 4 7 34567 2 4 7 45678 and I want the last row for each unique combination of A/B/C, where by "last" I mean greatest TS. A B C TS other columns 1 1 1 56789 1 2 1 23456 1 2 2 23457 2 4 7 45678 I did this simply in SAS: proc sort data=DF; by A B C descending TS

Hello *, I'm trying to round time stamps, consisting of a date and time part, to 10 minutes intervals The timestamps have the following format: %d.%m.%Y %H:%M *timeStamp <- c("31.03.2011 09:30", "31.03.2011 09:41", "31.03.2011 10:04", "31.03.2011 10:10", "31.03.2011 10:28", "31.03.2011 10:35", "31.03.2011 10:49",

We've been using CentOS 5 with Xen on our machines for a while now and have really grown to appreciate it. The lack of Xen for Centos 6 is the reason we haven't upgraded yet, but with Xen4CentOS6 we have all the tools we need. The concern some of are having is that when CentOS7 comes out, which will be probably less than a year, is that Xen support for CentOS6 will evaporate. I know this

Until today, the only way I offered PHP Markdown and PHP Markdown Extra was with packaged zip files available on my website. It turns out, unsurprisingly, that some people would prefer a simpler path for keeping their copy of PHP Markdown up-to-date. So today I announce two additional ways of grabbing PHP Markdown and PHP Markdown Extra. The first one is a PEAR channel which can be used

I have a dataframe as follows: Date time value 20110620 11:18:00 7 20110620 11:39:00 9 20110621 11:41:00 8 20110621 11:40:00 6 20110622 14:05:00 8 20110622 14:06:00 6 For every date, I want to extract the row that has the greatest time. Therefore, ending up like: 20110620 11:39:00 9 20110621 11:41:00 8 20110622 14:07:00 6 I am using for loops (for every date, find largest time value) to do

Hi all, I apologize for this off-topic question but I need your help -- I know there are lots of experts here. As a lover and student of statistics, I am thinking of building a tree of various branches of statistics and keeping track of the greatest historical inventions/discoveries in statistics and the latest development of each branch. The goal is to understand in what context did the great

Hi everybody, I've updated OggIndex to now output Skeleton 4.0 tracks. The differences between Skeleton 3.x and Skeleton 4.0 with OggIndex is: * The fisbone packet now includes a "Radix" field. * The fisbone packet now includes two new compulsory message headers; "Role" and "Name". * The fishead packet no longer includes "start time"

I am trying to find out if Polycom (I am using IP601) can display the speed dial list using last name first instead of first name first. Currently, the speed dial list displays first name first. Thanks.

Hello, This seems to be a weird one. I'm at work now and will get some more-verbose logs later when I get home if nobody has any ideas about what's happening here. I've got a tdm card with 1 FXO and 1 FXS. Asterisk is in the 1.2.x line, so is zaptel. astlinux to be specific. I can get the versions at home later if it might help. It's running on a silent epia 5000 board

Hi, I want to sort a data frame by multiple columns and then take the first record in each unique level of the "by" group I used to sort the data frame.

Hello everyone, could you help me learn if there are any directives that can be used to address the first and last element of a matrix array? I would like to thank you in advance for your help Best Regards Alex [[alternative HTML version deleted]]

Dear List, I have a series of dates and I am needing to know the greatest length of continuous dates - i.e. the number of dates before a break in the series.? For example, below there are three continuous series of dates with lengths 4, 6, and 8.? How can I count the number of continuous dates?? rle() will do it for constant integers, but I can't figure a way to modify it for continuous

Hi all, I've been using first() and last() for some time instead of x[1] and x[length(x)] for vectors, and I gradually added methods for lists, matrices, and data.frames. In preparing the next release of the 'gdata' package (2.16.1) I settled on these definitions, which harness the existing methods for head() and tail(): # Simply call 'first' or 'last' with a

Hi! My application needs to look up (by spelling) the first and last names of a person and then insert the corresponding pre-recorded audio file to personalize the message. E.g. "Hi, John Brown. Your book is due back at the library." So I need "John" and "Brown" in audio files along with LOTS of other names - Do such databases of sound files already exist or do I
