similar to: mean of a value of the last 2 hours using plyr (Thank you)

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 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

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 everyone, I have a data frame somewhat like this one: myframe <- data.frame (Timestamp=c( "24.09.2012 06:00", "24.09.2012 07:00", "24.09.2012 08:00", "24.09.2012 09:00", "24.09.2012 10:00", "24.09.2012 11:00", "24.09.2012 12:00",

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",

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

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"),

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

My xyplot has a number of panels, and I'd like a separate key for each rather than a single key for the entire set. However, I cannot find a way to pass multiple key definitions to xyplot's "key" argument. Allow me to throw out a simple example: require(methods) require(lattice) ## define sample data myFrame1 <- data.frame(a=1:100, b=rep(1:10,10), c=unlist(lapply(1:10, rep,

Hi all, I apologize in advance for the length of this post, but I wanted to make sure I was clear. I am trying to merge two dataframes that share a number of rows (but some are unique to each data frame). Each row represents a subject in a study. The problem is that sex is coded differently in the two, including the way missing values are represented. Here is an example of the merged dataframe:

Dear Amy, I have the same question as Mark. Is it possible to work from abroad - remotely?

I just discovered what seems to me to be a slight funny in respect of formal argument names. If I define a function foo <- function(a,b){ ... whatever ...} then ``inside'' foo() the exists() function will return TRUE from ``exists("a") whether an object named ``a'' exists or not. But get("a") will yield an error ``object "a" not found''

Dear all, I am new to rails and I am considering it for a project. What I would like to know (and I couldn''t straightforwardly find an answer to) is: - is it possible to develop commercial web applications in which you can pack a whole web app and send it to a client without disclosing the source? - is there any library of existing components already implemented? - which solutions are
