Syntax for capturing and writing file names
Hi all, I am looking for syntax to read a list of *txt files, (loop through?) each with a different data content but same fields, then run lines of code to produce summary stats (I have working code for this) and add the matching data file name when writing the results of a line of R code.?? Suggestions on any package vignettes that may be useful welcomed. My manual code for this is below

Memory issues in R
How do people deal with R and memory issues? I have tried using gc() to see how much memory is used at each step. Scanned Crawley R-Book and all other R books I have available and the FAQ on-line but no help really found. Running WinXP Pro (32 bit) with 4 GB RAM. One SATA drive pair is in RAID 0 configuration with 10000 MB allocated as virtual memory. I do have another machine

How to open files that contain "0"
Hi all, How can I set open files that contain values of Zero =0? These are valid values for the parameters I need to evaluate. I have tried CSV and tab formats. Trying XL Connect and/or XLConnectJars dies not seem to work to open Excel files so I am at a loss on how to get the data into a DF. Sample of data with 0 values: Filename Dur TBC Fmax Fmin Fmean Fc S1 Sc Pmc g8221843.13#

Using merge
Hi, I have two tables and I need to merge both. I use the merge command, but in this way the name must be exactly. How I can make to compare independently of upper or lower-case? Look: data1<-data.frame(journal=c("Ecology","Environmental Entomology","Neotropical Biology And Conservation"))

call an IP camera?
Hi, is it possible to "call" an IP camera? I'm thinking about something like bridging with a music stream, but instead of streaming audio, bridge with the video stream from the camera. It would be very cool if I could just call the camera and see what's going on. Ffmpeg shows the following streams available from the camera: Stream #0:0: Video: h264 (Main),

Accelerated video output with ffmpeg2theora 0.24
When I converted two files with ffmpeg2theora their duration changed shorter - they seem to play back with accelerated speed. When I play one of them with VLC, the video stops at 99 seconds but audio continues until 170 seconds. The other file is 120 seconds long but it is played back in 80 seconds. Here is ffmpeg2theora output: $ ffmpeg2theora --optimize --inputfps 25 -F 25 2002-05-23\ Juho\

Hi! This happened to me also! I just got a spam email just after posting and then in following days I got obnoxious spam emails in my spam filter. As the others, I think that there is some kind of bot subscribed to the list, but also perhaps a spider or crawler monitoring the R-Help archive and getting email addresses there. Nabble is a possibility too. > On 17 Apr 2018, at 21:50, Peter

I asked the moderators about it. This is the reply "Other moderators have looked into this a bit and may be able to shed more light on it. This is a "new" tactic where the spammers appear to reply to the r-help post. They are not, however, going through the r-help server. It also seems that this does not happen to everyone.

Merging data tables
Hi all, I am trying to merge several data sets and end up with a long data format by date & time so I can run correlations and plots. I am using Deducer as an R GUI but can just use the R console if easier. The data sets are weather with wind speed, relative humidity and temperatures by date and minute and bat activity with date, time, label, and an activity index number. The bat

Just an observation. I have not seen the spam you are discussing.
