Hi, I am stuck with creating a conditional categorical variable in R If my dataframe data_2 has 3 variables A,B,C I want to create variable D which would be something like : data_2$D <- ifelse(data_2$A < data_2$B & promotion_ind =="N",1,0), this throws up an error "In Ops.factor(data_2$A,data_2$B) : < not meaningful for factors I have tried converting the

Combining and completing the advice from Greg and Boris the complete solution is two lines: data_2 <- read.csv("excel_data.csv", stringsAsFactors = FALSE) match_list <- match( data_2$data1, data_2$data2 ) The vector match_list will have the matching position when it exists and NA's otherwise. Its length will be the same as the length of data_2$data1. You should get

It's generally a very good idea to examine the structure of data after you have read it in. str(data2) would have shown you that read.csv() turned your strings into factors, and that's why the == operator no longer does what you think it does. use ... data_2 <- read.csv("excel_data.csv", stringsAsFactors = FALSE) ... to turn this off. Also, the %in% operator will achieve

Hi, I have two columns that contain numbers along with letters (as shown below) and have different lengths. Each entry in the first column is likely to be found in the second column at most once. For each entry of the first column, if that entry is found in the second column, I would like to get the corresponding index. For instance, if the first entry of the first column is 5th entry in the

HI, I would like to extract data in a specific way.  For example, the rainfall data 0,0,1.5,0,0, 3,1,2.5,0,0,0,0, 2.3,0,0,0, 2.1,1.4,0,0,0, 3,2,1,0,0,0... data_1: 1.5, 2.3               ( a single nonzero data between zeros data) data_2: 3.1, 2.5, 2.1,1.4   ( two nonzero data between zeros data) data_3: 3,1,2.5, 3,2,1       ( three nonzero data between zeros data) Thank you so much for any

Hello everybody, I have usually solved this problem by repeating lines of codes instead of a loop, but it's such a waste of time, I thought I should really learn how to do it with loops: What I want to do: Say, I have several data files that differ only in a number, e.g. data points (or vector, or matrix...) Data_1, Data_2, Data_3,... and I want to manipulate them e.g. a simple sum of

Good evening! So, I have a problem with installing this game on ubuntu-linux. I tried it with Wine which turned out not to be able to set the doublebuffer in the configuration menu. First there were no problems, but after having installed quite half of the game there was an issue: Though the Error came in German (cause the game in German - anyway, I am a German guy ^^) The

I am trying to plot data with multiple logical and physical groups using R. Below is a sample of the kind of data I am working with and the desired output. We have a jmp script that can do the same thing, but at ~$200 a year the licensing is counterproductive. Thanks for any help. Data input: Loaded from a CSV file. Physical_1 Logical_1 Logical_2 Data_1 Data_2 x Y Z2

Hola buenas, me preguntaba si alguno usa hadoop Spark en su día día y si me podíais recomendar un buen curso para empezar. Estuve en la charla de meetup de madrid hace unos meses de Rspark y estuvo bien, ahora me preguntaba si es posible profundizar. Pero me gustaría tener recomendaciones de cualquier material que podáis recomendar, cursos de coursera que hayais hecho, libros que hayais leido,

I would like to calculate the mean of tree leader increment growth over 5 years (I1 through I5) where each tree is a row and each row has 5 columns. So far I have achieved this using rowMeans when all columns are numeric type and used in the calculation: Data1 <- data.frame(cbind(I1 = 3, I2 = c(0,3:1, 2:5,NA), I3 =c(1:4,NA,5:2),I4=2,I5=3)) Data1 Data1$mean_5 <- rowMeans(Data1, na.rm =T)

Hola buenas, hace unos días el Rstudio me dejó de funcionar en una de mis maquinas Windows8. No puedo volver a un estado anterior así que mal y tampoco me vale reinsatalarlo ( aunque reinstale ambos programas R y Rstudio) porque sigue sin funcionar. No tengo muy claro que hacer. ¿Alguna ayuda? ¿Esto es una duda de R? Muchas gracias por adelantado PD a continuación os muestro mis errores Mi R
