similar to: paste first row string onto every string in column

Try this , save your data in C:/ and write this (data <- read.csv2("c:/jill.csv", sep=",")) (C<-data[1,]) A <- numeric(4) B <- numeric(4) for (i in 1 :4){ A[i] <- paste(data[1,i],data[2,i]) B[i] <- paste(data[1,i],data[3,i]) } A B (data1 <- rbind(as.character(A),as.character(B))) (data2 <- rbind(C,data1)) normaly that gives that > (data <-

Hi all, I think this is a very basic question, but I'm new to this so please bear with me. I'm using match to translate elements of a data frame using a lookup table. If the content of a particular cell is not found in the lookup table, the function returns NA. I'm wondering how I can just ignore those cells, and return the original contents if no match is found in the lookup table.

Hi all, I would like to combine elements of a vector: vec <- c("astring", "b", "cstring", "d", "e") > vec [1] "astring" "b" "cstring" "d" "e" such that for every element that contains "string" at the end, it is combined with the next element, so that I get this:

Hi, i'm very new to R, so sorry for what i'm sure is a very basic question. I'm producing a boxplot with the data below: df3<-data.frame( x=c(10,11,115,12,13,14,16,17,18,21,22,23,24,26,27,28,29,3,30,32,33,34,35,4,4 1,45,5,50,52,56,58,6,67,6738,68,7,8,9), fq=c(8,11,1,2,4,4,2,2,6,3,4,2,2,1,1,1,4,51,3,1,1,1,1,35,1,1,19,2,1,1,1,14,1, 1,1,10,13,5),

Dear R friends, I am currently working with time series data, and I have a table(as data frame) that has looks like this (TransitDate are in format = "%e-%B-%Y") : TransitDate Transits CargoTons 1985-04-01 100 2500 1985-05-01 135 4500 1985-06-01 120 1750 1985-07-01 100 3750 1985-08-01 200

I have a series of tables, one for each environment indicating a date (row) and a sample at each hour of the day (0 to 23) Test1 Table: Date,Hour1,Hour2,...Hour23 1/1/10,123,123,...,123 I would like to model this as a time series but how can I translate the table into a list such that I can get: 1/1/10 00:00, 123 1/1/10 01:00, 123 1/1/10 02:00, 123 ... 1/1/10 23:00, 123 Any suggestions on how

Hi Paul, #First I set up some sample data since I don't have a copy of your data dtOrig <- as.Date( c("1985-04-01","1985-07-01","1985-12-01","1986-04-01")) dfOrig <- data.frame( TransitDate=dtOrig, Transits=c(100,100,500,325), CargoTons=c(1000,1080,3785,4200) ) #Generate the complete set of dates as a data frame dfDates<- data.frame(

Hello, R-helpers. I have a data frame below called df. I want to add a variable c, based on the following logic: if df$a < 5 then the first two times this condition is met place a 1 in c, the next two times this condition is met place a 2 in c and when the condition is not met let c equal df$b. The result would look like, dfnew, shown below. a <- rep(c(3,5,7), 4) b <- rep(c(NA,1,2),

Hello All, Would like to be able to convert a matrix to a dataframe without losing an assigned dimname. Here is an example that should illustrate what I'm talking about. tableData <- state.x77[c(7, 38, 20, 46), c(7, 1, 8)] names(dimnames(tableData)) <- c("State", "") tableData State Frost Population Area Connecticut 139 3100 4862

Dear Eric, Hope you are doing great. I also tried the following: #First I created the complete date sequence TransitDateFrame <- data.frame(TransitDate=seq(as.Date(dataset1[1,1]), as.Date(dataset1[nrow(dataset1),1]), by = "month")) #Then I did the merging dataset1NEW <- merge(TransitDateFrame, dataset1, by="TransitDate", all.x=TRUE) Now it has, as expected the

Hi, I am a beginner in R and have only read a few chapters in the R book, I was not able to find a solution for this simple problem. I have an empty data frame: a=data.frame(name="test") which I would like to extend in a for-loop (with data extracted from a database). Ideally I would like to extend the data frame like this: a["new_1"] = 1:10 a["new_1"] = 1:12

Dear all, for each A == 3 in 'df' I would like to change the variables B and K. My result should be the whole df and not the subset (A==3)... df <- data.frame(A = c(1,1,3,2,2,3,3), B = c(2,1,1,2,7,8,7), K = c("a.1", "d.2", "f.3", "a.1", "k.4", "f.9",

Hi Instead of attachments copy directly result of dput(TransitDateFrame) and dput(dataset1) to your email. Or, if your data have more than about 20 rows you could copy only part of it. dput(TransitDateFrame[,1:20]) dput(dataset1[,1:20]) Only with this approach we can evaluate your data in all aspects and provide correct answer.

Hello list The Samba Howto Collection repeatedly asserts that by setting the sticky bit on directories any files created in those directories will be created with the owner set to that of the directory (for example, see http://samba.mirror.ac.uk/samba/docs/man/howto/AccessControls.html#id2541262). This has never worked for me. Files created inherit the group of the directory, but not the owner.
