Hi team, A Samba "panic" occurs after repeatedly saving "word" files on the server. Following the panic the "active connection" disappears, but the "active shares" and "open files" stay. Windows reports different errors such as "delayed write failed", "Cannot complete the save due to a file permission error" etc. Many of the

Dear All, I have conducted an experiment in order to examine predation pressure in the surroundings of potential wildlife road-crossing structures. I have documented predation occurrence (binary?) in these structures and calculated several possible explanatory variables describing the spatial heterogeneity in several scales. At the landscape scale I have calculated the percentage of different

Performing Merge and Duplicated on very large files
Hi, I am working with very large matrices (>1 million records), and need to 1. Join the files (can be achieved with Merge) 2. Find lines that have the same value in some field (after the join) and randomly sample 1 row. I am concerned with the complexity of merge - how (un)efficient is it? I don't have access to the real data, I need to send the script to someone who does, so I

double precision
Hi, I am attempting to query a data frame from a mysql database. One of the variables is a unique identification number ("numeric") 18 digits long. I am struggling to retrieve this variable exactly without any rounding. The function I am using is sqlQuery(), with an ODBC connection. Querying directly results in the double being rounded towards the end (eg 6527600583317876352 instead of

R binary version with R_MEMORY_PROFILING
Hi all, Where can I find an R binary version (>2.4.0 ) for windows that compiled with R_MEMORY_PROFILING? Within our application we are experiencing serious problems with memory usage. And being able to use "Rprofmem" and "tracemem" command seems like our best option. Thanks, Yoni [[alternative HTML version deleted]]

[RFC-PATCH] Introducing virtio-example.
The main goal is to create an example to be used as template or guideline for contributors when they wish to create a new virtio device and to document "the right way" to do so. It consists of several parts: 1. The device specification * it can be found in the device header of the implementation * it will hopefully be added to the official virtio specification

R Processing dataframe by group - equivalent to SAS by group processing with a first. and retain statments
Check out the dplyr package, specifically the mutate function. # Create new column based on existing column value df <- df %>% mutate(FirstDay = if(ID = 2, 5)) df Repeat as needed to capture all of the day/firstday combinations you want to account for. Like everything else in R, there are probably at least a dozen other ways to do this, between base R and all of the library packages
