similar to: count NAs per week

Hello, I'm quite new to R and still spend hours trying to figure out single things so I hope nobody rolls his eyes over my question. I have a data set over time and converted it to the POSTIXct format. I added a column in the data set for the week and the month. I try to get a plot which shows the weeks on the x-axis and the number of datasets without NAs on the y-axis. That doesn't

Hello, I tried to construct my very first loop today and completly failed :-( Maybe someone can help me? I have a dataframe somewhat like this one: myframe <- data.frame (Timestamp=c("24.09.2012 09:00", "24.09.2012 10:00", "24.09.2012 11:00", "25.09.2012 09:00", "25.09.2012 10:00", "25.09.2012

Hello, I tried for about three hours now to solve this problem but I can't figure it out. I am sure someone knows how do it. At least I hope so. I have a data frame somewhat like this: myframe <- data.frame (ID=c("Ernie", "Ernie", "Bert", "Bert"), Timestamp=c("24.09.2012 09:00", "24.09.2012 09:00", "24.09.2012 10:00",

Hello, I have a data frame somewhat like that: myframe <- data.frame (ID=c("Ernie", "Ernie", "Ernie", "Bert", "Bert", "Bert"), Timestamp=c("24.09.2012 09:00", "24.09.2012 10:00", "24.09.2012 11:00"), Hunger=c(1,1,1,2,2,1) ) myframestime <- as.POSIXct (strptime(as.character(myframe$Timestamp),

Dear all, I have a data similar to this: myframe<- data.frame (ID=c("Ernie", "Ernie","Ernie","Ernie"), Timestamp=c("24.09.2012 08:00", "24.09.2012 09:00", "24.09.2012 10:00", "25.09.2012 10:00"), Longitude=c("8.481","8.482","8.483","8.481"),

Thank you for providing the example code... for the request of running it multiple times it would have helped if you could have confirmed that the example ran through without errors... there were a lot of mistakes in it. Look into using the reprex package to check your example next time. I don't do this kind of analysis... I really don't know what to expect from the functions. The

I have a data frame somewhat like this: myframe <- data.frame (ID=c(2,3,4,5), Hunger =c(415,452,550,318 )) myframe Now I would like to add a column to the right which summarizes the values for Hunger somewhat to reduce the number of values: If the values for Hunger are between 300-400 I would like to insert the number 350, between 400-500 insert 450 between 500-600 insert 550 Does

Dear knowing people, Dennis Murphy helped me a lot with my first loop last week. Thanks again - I could have made more than 10 "Thank-You cakes" in the time it saved me! But now I want to complicate the thing. My ideas didn't work. Let's see if anyone is smarter ;-) The following packages are needed: library(adehabitatHR) library(rgdal) library(plyr) # My dataframe looks

Hi dear three helpers, Thanks a lot! Your solutions worked great. Again I learned a lot.

Hi all, I have a problem with a variable created by a SELECT CASE statement. See the code below. I would like the variable "event" to be a character variabel as I want to UNION my two SELECTs - and the "event"-variable is a character variable in the first SELECT result. I have tried different ways: * used ' ' in stead of " " around the string I want as the

At the bottom is what I got returned from AMANDA 2.3.0.5 after patching Samba 1.9.16p11 to give estimates. Any idea what I might not have done yet? My disklist reads: shokk \\thor\depot nocomp-user-gnutar To connect successfully to that server with smbclient, I have to do this, giving the same password that I now have in /etc/amandapass: smbclient \\\\THOR\\DEPOT -U BACKUP Also, the

That would be a *really* bad idea. See the l0phtcrack source for details :-). Seriously, though. The password hashes used on NT are very poor. They don't use salt and people are now

I could use some eyes on https://rails.lighthouseapp.com/projects/8994/tickets/4368 if anyone has the time. Summary of the change: Similar to PredicateBuilder''s existing support for ''table.column'' => ''value'', this patch enables ''column#method'' => ''value''. For instance,

Would the core team be open to the removal of the ''&'' alias for ActiveRecord::Relation#merge? The reason is that in Ruby the ''&'' operator refers to an intersection of two sets of data, not a merge. (within the context of the Array class) Recently Arel added support for SQL Set Operators: 2-0-stable:

Ive just installed a TDM4000P with 4 fxos. The zaptel config is fine, zttest comes back with configured. If i call a line when zttest it shows on the display,and then goes when the line drops. In * when a call comes in, it follows my dialplan and answers the call according to the log, but IT DOESN'T actually pick up the call, i.e. it continues ringing. I'm using KS signalling, and

I've created a data frame in R, but in order to clean up some of the data, I need to set certain variable observations equal to the value of their previous observation (it would be conditional, but that part's less important right now). In Stata, I would simply set var = var[_n-1] in those cases. What is the R equivalent? [[alternative HTML version deleted]]

Hey all, In troubleshooting a failing test for MetaSearch against 3-0-stable, I came across some undesirable (from my side, anyway) behavior in http://github.com/rails/rails/commit/bf87528b53f1422708ec0188d126cfca824ddc5c. A simple one-liner, it would appear, but AR::Base implements before_remove_const to do a bit of scoped method cleanup... It''s the only thing I can see that might

Am using R on a Linux box and am currently writing an interactive R script. 1. How do I ask a user to press any key to continue ? I used a system call to read but this only works if the Enter key is pressed: print("Press any key to continue") system("read") 2. How do I get a string input from the user? Would like to see an R function, say askget(): delay =

Hi, I''m newbie to rails, so please be gentle with me. I got one of the new powerbooks that apple just released last month (october 2005). I installed rails using RubyGems and also the installer for mac osx found here http://www.tonyarnold.com/articles/2005/08/10/rolling-with-ruby-on-rails-on-mac-os-x-tiger-for-beginners everything seems to update and install fine.
