Dear R User's Please help me to debug this issue. I am trying to write some data ( i= 6) to PostgreSQL database, but it not writing. Is there any issue in the way I use "dbWriteTable"? ++++++++++++++++++ Source Code ++++++++++++++++++++++++ library("DBI") library("RPostgreSQL") drv1 <- dbDriver("PostgreSQL") i=6 connAE1 <- dbConnect(drv1,host

Hi, Let me justify building R from source. While I can obtain R built for me under Ubuntu, I tend to build it from scratch as we use a NFS-shared build as well as shared R libraries for all the bioinfo staff at this company. Only one build and one set of packages to ensure uniformity across all workstations. My problem is that despite using a pretty standard build process, I am failing at the

Are there any functions available to calculate sunrise and sunset times for given latitude,longitude and dates? If not, I'll appreciatte any pointers to C code I could use/port. Thanks, Angel

##This is a function that I am trying to write to calculate sunrise and sunset and works "mostly", but returns nonsensical values. What am I #missing? Thanks in advance. ###remember to include maptools as dependence### library(maptools) sunrise.set <- function(lat, long, date, timezone="UTC", num.days=1){ #this needs to be long lat# lat.long <- matrix(c(long, lat),

Hello to all, I have two dataframes, the first with two columns sunrise and sunset (for 10 years). Each of these columns is formatted for date time (ex: 01-Jan-2010 15:37:00) In the second data frame I have GPS information and also a date time column (same format ). What I would like to do is a subset of all the rows from the second dataframe that occurred in day time only so between sunrise

Hi, I have a data.frame that contains a variable act which records the duration (in seconds) of two states (wet-dry) for several individuals (identified by Ring) over a period of time. Since I want to work with daytime (i.e. from sunrise till sunset) and night time (i.e. from sunset till next sunrise), I have to split act from time[i] till sunset and from sunset until time[i+1], and from time[k]

I have looked at ?as.POSIXct ?POSIXct and many of the references that are on those pages. I am bewildered with timezones. Is there a way to get what would go into tz="" for making a function that uses POSIXct to be able to be used in all of the timezones in just the united states? This is for both windows and mac... this is the function that I am wanting to use it with

Dear R helpers, I have a dataframe (test1) containing the time of sunrise and sunset for each day of the year for 3 years. I have another dataframe (test2) containing measurements that are taken every 15 minutes, 24/7. I would like to extract all rows from test2 that occur between sunrise and sunset for the appropriate date. Can you suggest a good vectorized way to do this? Keep in mind

Does anyone know if there is a sunrise sunset calculator for R? -- Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods. We are mammals, and have not exhausted the annoying little problems of being mammals. -K. Mullis [[alternative HTML version deleted]]

Dear List, I am trying to find each time a value changes in a dataset. The numbers are variables for day vs. night values, so what I am really getting is the daily sunrise and sunset. A simplified example is the following: x<-seq(1:100) y1<-rep(1,10) y2<-rep(2,10) y<-c(y1,y2,y1,y1,y1,y2,y1,y2,y1,y2) xy<-cbind(x,y) I would like to know each time the numbers change. Correct

Hello, I'm having problems working with date values in POSIXct format. Here is what I got (eg.lig attached): x <- read.table("eg.txt", sep = ',', col.names=c("ok","time","secs","lig")) # it gives time as factor z <- cbind(x,colsplit(x$time, split="\\s", names=c("date", "clock")))

(Posted few days ago on qemu group but no reactions) Do I understand correctly that ssl shoudl be configured independently for libvirt and each hypervisor? I asked because I configured libvirt connection as qemu+tls://bambus.kjonca/system?pkipath=... (and on bambus in /etc/libvirt/libvirtd.conf) I set key_file = ... cert_file = ... ca_file = ... But after connect and lauching (on bambus) vm I

Hello all, After beating my head against the wall for a few hours, I give up. I have two problems. 1. If I use seq() to generate a POSIXct series that crosses a daylight savings to stardard time change I get two values for the first day of change. The time change is Nov 6,2011. The value for Nov 7 turns into 23:00 on Nov 6, thus two values for Nov 6. (see below) So I put a time value (noon)

Okay, I found the right ahsetup.exe (Active Home). It's doing the same thing for me: extracting CloseApp.exe (which is the same program I found) to the temp folder, but then shutting down with an error message about being unable to use it. As to why, the answer, IMO, is that this is a very old program (the download site says it works in Windows 3.1), and most programs that old simply

I'm trying to find a clever way to re-map data from a database query into a data.frame. Querying a database often returns a table (data.frame) like this: GeneID MethodID Value 6 1 123 6 2 456 6 3 987 7 1 234 7 3 432 8 2 190 8 3 34 8 1 864 Note that GeneID=7 doesn't have a value for MethodID=2. Note that GeneID=8 doesn't have the

Greetings list, It seems that more and more phones these days are coming with XML mini-browsers. I'd like to have a go at developing something useful to use on them, but in all honesty, most of our customers use their phones to make and take calls and very little else. So I'm open to suggestions. What useful applications are you developing for these mini-browsers? What sort of things do

It depends what you are asking about. There are various connections, each of you can configure separately. >I asked because I configured libvirt connection as
