If I have a data frame where a species occupies several rows with different phases such as (both col's ar factors): species,phase Populus tremula,1 Populus tremula,2 Populus tremula,3 Calluna vulgaris,1 Calluna vulgaris,2 Betula alba,1 Betula alba,2 Betula alba,3 Primula veris,1 Primula veris,2 and another df where each species only have one row: species,growth_form Populus tremula,tree Acer

Hello, I am unable to figure out how to code a new column in a data frame based on an existing column that matches a column in a reference data frame, in a relational-db fashion. I would like this to maintain a minimum set of reference tables that may be reused over several similar datasets. Specifically, I have two data frames as listed below, 'Bos' and 'tree.' For each case in

Greetings I have a dataset with occurrence records of multiple species. I need to get rid of multiple listings of the same occurrence point for a species (as you see below in red and blue typeface). How do I create a dataset only with unique set of longitude and latitude for each species? Thanks in advance. Species_name Longitude Latitude Abies concolor -106.601 35.868 Abies concolor -106.493

LS, I would really like to know how to count the frequency/occurrence of chachters inside a dataset. I am working with extreemly large datasets of forest inventory data with a large variety of different species inside it. Each row inside the dataframe represents one individual tree and the simplified dataframe looks something like this: num species dbh 1 sp1

Hello R Help! I would like to make a legible boxplot of tree growth rates for each of seven tree species at each of seven different sites. It's a lot of data to put on one figure, I know. I made a beautiful, interpretable figure using color, but my target journal can't deal with color figures. I can use seven shades of grey to fill the boxes, but the figure then becomes uninterpretable -

There is incompatibility between R strptime and musl libc. I posted about it on their mailing list, but they need more information I can't provide, so I'm forwarding the message here in hope R developers can help.

@Simon. Here's what I did. I checked out R revision 70059. Ran export r_cv_libc_stack_end=no. (otherwise it would give that error we talked about before) Ran ./configure --without-recommended-packages. (otherwise it would complain of not finding ./src/library/Recommended/MASS_*.tar.gz) Ran make. Ran make check. Log is here - http://pastebin.com/raw/cGJgqB8p What do you think? Is there

Here's what I did. svn checkout https://svn.r-project.org/R/trunk/ cd ./trunk aclocal -I m4 && autoconf tools/rsync-recommended cd .. mkdir build cd build ../trunk/configure make make check On make check it gives an error.

Hi, Does anyone have any advice on customising firmware of an SPA921 so that it can be locked to a sip provider and display logos on the config pages.

Hello, I would like to know how Asterisk deal in this case: Assume I have a Main Asterisk Server located in UK, and another box that have PSTN interfaces located in China, now the purpose is to FW calls through PSTN. Assuming I have a client who is calling from Japan to my main switch in UK and he is calling China, (japan have latency around 500ms to UK and 100ms to China), how asterisk

Hello, developers of R. I have been unsuccessfully trying to build R on a musl libc system for the last days. ./configure works, but make fails. The command that errors out is here - http://pastebin.com/raw/UwFRsiqT It was brought to my attention that this is a (very longstanding) abuse of a private glibc symbol in R. In R 3.2.3, it seems that configure is trying to test for it on Linux. It

Any more information I can give to help debug this? Thanks. On Mon, Feb 1, 2016 at 3:49 PM, Martin Maechler <maechler

Hello. I have a server installed with asterisk 1.6. I have a PSTN line that comes in to one of those clone cards. Everything seem to be working fine. The only problem I have is that I can't get voicemails coming from the PSTN line. All other: SIP, IAX work fine. I can hear those ok but, when it comes to a call that comes in from PSTN I get no sound. What can cause that problem? Thanks in

Hello, We previously had Win2008 R2 DCs which we have begun to replace with Win2012 servers (forest is still at 2008 level however). I was able to query DFS via rpcclient but now I find that I am unable to. I know that SMB3 was introduced in Win2012 but I believe that it should auto-negotiate earlier versions. I did however test from v4.1.9 as well, unfortunately that still fails. From Samba3

Hi everyone, Some instructions in llvm have names and for some of them the name is empty. Now, I wanted to know which instructions have names?

Hi everyone, Instruction and Value classes have "Uses" and "User". What is the difference between them? I think that "Uses" gives all the instructions/values that a particular Value depends on and "User" gives all the instructions/values that depend on that particular value. Is that right?

Dear Geskus, I want to develop a prediction model. I followed your paper and analysed thro' weighted coxph approach. I can develop nomogram based on the final model also. But I do not know how to do internal validation of the model and subsequently obtain calibration plot. Is it possible to use Wolbers et al Epid 2009 approach 9 (R code for internal validation and calibration) . It is
