Greetings R Users,
I´m new to R but at least managed to read in multiple files:
filenames <- list.files(path=getwd())
numfiles <- length(filenames)
for (all_temp in c(1:numfiles)) {
filenames[all_temp] <- paste(filenames[all_temp],sep="")
assign(gsub("[.]ASC$","temp",filenames[all_temp]),read.delim2(filenames[all_temp],
fileEncoding="ISO-8859-15", skip = 4))
}
Now I want to change the column names on the fly within the above loop. How?
I only found out for one file:
colnames(w01_10temp) <- c("date", "time", "temp", "na")
I want then to lineary interpolate "date", "time" and "temp" from the
original 5 to 1 second interval for all the files, like:
old:
date time temp na
1 22.05.11 16:00:00 23.653 NA
2 22.05.11 16:00:05 23.541 NA
...
new:
date time temp na
1 22.05.11 16:00:00 23.653 NA
2 22.05.11 16:00:01 23.631 NA
3 22.05.11 16:00:02 23.609 NA
...
I already found out about the zoo package, but could not really figure out
how to use it correctly...
Thanks for any help.
