vertically concatenating data frames
Hi, what is the recommended way to vertically concatenate 2 data frames with the same column names but different number of rows? My problem is something along these lines: df1 <- data.frame(var1=var1,var2=var2,var3=var3) # nrow(df1)=1000 df2 <- data.frame(var1=var4,var2=var5,var3=var6) # nrow(df2)=2000 I tried df <- c(df1,df2), no success. stack does not seem to be appropriate

poor rbind performance
Hi I rbind data frames in a loop in a cumulative way and the performance detriorates very quickly. My code looks like this: for( k in 1:N) { filename <- paste("/tmp/myData_",as.character(k),".txt",sep="") myDataTmp <- read.table(filename,header=TRUE,sep=",") if( k == 1) { myData <- myDataTmp } else{ myData

compute time span in months between two dates
Hi, I am just starting to play with R. What is the recommended manner for calculating time spans between 2 dates? In particular, should I be using the "chron" or the "date" package (so far I just found how to calculate a timespan in terms of days)?

converting list to an array
Hi, I have a list myList (see below) that consists of id's $'7',....,$'10' and each id has an individual array, the length of which can vary from id to id. How can I convert this list into an array, ie. stacking the individual arrays into one large array? Thanks Zava myList: $`7` [1] 20050201 20050301 20050401 20050501 $`8` [1] 20050201 20050301 20050401

Elegant way to transform dataframe?
Hello, I have a dataframe with columns like: parameter1 parameter2 metricname value and I'd like to transform it into a dataframe with columns: parameter1 parameter2 metric1 metric2 metric3 where the values for each metric would be in the appropriate column. There are often multiple values for a given (parameter1, parameter2, metricname) triple. In this case, I want to use the

'fixing' list components
I have a list x (say) that will contain many inputs to and outputs a model. x$input1 <- assign.input1(parameter1, parameter2) is one way to assign input1, but it would be neater to be able to do assign.input1(x, parameter1, parameter2) Is this a good idea? If so, what is a good way to do it? -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing

basic handling of data.frame
Hello, I'm new to R but wan't to use it to compute the statistics of my medical study. The study includes several parameters for a number of patients. Each parameter was assessed by a number of readers, once with a special condition, once without. Now I have a data.frame with colums like: PatientID, ReaderID, SpecialCond(yes/no), Parameter1, Parameter2..... the rows are not sorted, and

Class parameter flexibility with ENC, hiera or both
Dear puppetteers, I am having a philosophical question about parametrized classes. When building modules, one wants to be as flexible as possible, to try to target as many puppet flavors as possible. This is our target: - Foreman users, using foreman as an ENC with smart variables (or potentially any other ENC, but I would say this is the most widespread one). - Pure Puppet''s site.pp

A statement over multiple lines (i.e. the ... feature in Matlab)
Hello again list, I thought I'd start a new thread, seeing as it's completely different from my previous question. Some functions I have written require many parameters, and so do not fit nicely into an 80 column width display. This is usually avoided, by spreading that particular statement over a few lines. This is something that I do in Matlab with the following: myFunc(

[LLVMdev] object construction patterns and unique_ptr
In lld we have a Reader class which is a factory that takes .o file(s) and produces an in memory lld::File object(s). But in doing so, there could be I/O errors (file not readable) or file may be malformed. We are also using C++11 in lld, so we use std::unique_ptr for managing object ownership. The Reader class currently has an interface that can be simplified down to: virtual error_code

structure data
Hello, I have a quite simple question, I guess. I have a data frame and I would like to process the data in several ways. The processing is dependent on grouping (factors) and the parameter itself. Meaning for parameter1 in the df, I would like to calculate the mean and sd when grouping by factor1. But parameter2 might be different. I thought of a structure like this: group1 param1
