Hello; I have a problem merging data sets. I use this command: FileNames <- list.files(path="C:/updated_CFL_Rad_files/2007/11", full.names=TRUE) > dataMerge <- data.frame() > for(f in FileNames){ + ReadInMerge <- read.csv(file=f, header=T, na.strings="NULL") + dataMerge <- merge(dataMerge, ReadInMerge,all=T) + + } and an error occurs.The size of the

Hi; I have 30 data sets and I managed to take the average of a variable in each set and put them in a vector like variable(It contains NaN data as well). x<- matrix( list.files("C:/updated_CFL_Rad_files/2007/11",full=TRUE)) for(i in 1:30) { radiation.data <-read.table(x[i], header = TRUE,sep = ",", quote = " ", dec = ".") attach(radiation.data)

Hi all; It seemed to be easy at first, but I didn't manage to find the answer through the google search. I have a set of data for every second of the experiment, but I don't need such a high resolution for my analysis. I want to replace every 30 row of my data with their average value. And then save the new data set in a new csv file to be able to have a smaller excel data sheet. What is

My problem is that I have a data set for every day of measurement in a seperate file and I want to plot one parameter of the data for all the days in one graph. I tried to use for loop but only the last data remains in the program memory, I don`t know how to plot each day`s data continusly after the others(or how to extending the x axis.) Would you please help me with it? This a plot for one day:
