similar to: Unique rows in data frame (with condition)

I have a set of labels arranged along a timeframe in a. Each label has a timestamp and marks a state until the next label. The dataframe a contains 5 such timestamps and 5 associated labels. This means, on a continious scale between 1-100, there are 5 markers. E.g. 'abc' marks the timestampls between 10 and 19, 'def' marks the timestamps between 20 and 32, and so on. a <-

Hi experts, I am trying to write a very flexible method that allows me to add a new column to an existing data frame. This is what I have so far: add.column <- function(df, new.col, name) { n.row <- dim(df)[1] length(new.col) <- n.row names(new.col) <- name return(cbind(df, new.col)) } df <- NULL df <- data.frame(a=c(1,2,3)) df # corect: added NA to new collumn df <-

I have a matrix 700x2000 which is sampled in each cycle from another matrix 788x2000 with the numbers 0,1 and 9 There is one specific collumn of this matrix, dart[,1977], that usually, after the samplimg procedure has only 1 and 9 (because the zero frequency in this collumn is low). However, when this happens, I want to include an IF conditional in my code. so basically what i wanted to do was to

Dear all, I have a data.frame like the sample below, and I would like to expand my data.frame using "population" variable. So, for each line of my data.frame I would like that the new data.frame have many rows as the population collumn. place<-c("place1", "place2", "place3", "place4", "place5") population<-c(100,200,300,50,30)

Hi, llvm-gcc 4.2 generates warnings when I compile inline assembly code that contains used labels with -Wunused-label. The generated code seems to work yet. gcc 4.2 doesn't generate those warnings. I haven't found any bugs regarding this issue in the llvm bug database. Does anyone know if this is a known llvm issue? Is it a warning that I can ignore and does not affect the generated

In Syslinux 5-6.02, the "global append" directive is being (unintentionally) ignored in some cases. Updating Syslinux from prior versions, when using a "global append" directive, will cause unexpected results. For example, take the following simple configuration file: *** DEFAULT mykernel APPEND root=/dev/sda2 *** Note that the 'append' line is a global

I''ve got a block of code that''s turning out.. well - just plain ugly. So i know I must not be doing it the Ruby way. The main problem I''m having is in dealing with handling errors - and just not finding much Rails documentation that gives a deeper understanding of how to handle errors in Rails (outside of several docs on the catch-all''s) the main method

was trying to match different matrices of different lengths with in the first collumn date and time info (yearmonthdayhourminute). the routine needs to return NA?s where data of either of the matrices is non existent. have been trying the following: #### x <- c(200112030003, 200112030004, 200112030005, 200112030006) y <- c(0.1, 1, 1.1, 1.5) a <- c(200112030004, 200112030005,

hello guys, I need to do a BLUP in the simplest model y = Xm + Zg + e however I have missing data in the analysis which I can?t consider as 0(zero). So I need to generate the matrix X'Z, Z'X and Z'Z step by step; I can?t use crossprod(x) #neither X'X <- t(x)%*%x because I should skip the elements with missing data in the matrix I?ll try to be more clear, supposing a matrix x

My question is twofold. Part 1: My data looks like this: (example set, real data has 2*10^6 rows) binary<-c(1,1,1,0,0,0,1,1,1,0,0) Chromosome<-c(1,1,1,1,1,1,2,2,2,2,2) start<-c(12,17,18,20,25,36,12,15,16,17,19) Table<-cbind(Chromosome,start,binary) Chromosome start binary [1,] 1 12 1 [2,] 1 17 1 [3,] 1 18 1 [4,] 1

Hallo, linux-btrfs, please delete the option "-L" (for labelling) in "mkfs.btrfs", in some configurations it doesn''t work as expected. My usual way: mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ... One call for some devices. Wenn I add the option "-L mylabel" then each device gets the same label, and therefore some other programs
