Any help in resolving the following errors will be appreciated:
> pollutantmean <- function(directory, pollutant, id=1:332)
+ file_inc <- list.files("specdata", full.names=TRUE)
> dat <- data.frame()
> for(i in 1:10) {
+ dat <- rbind(dat, read.csv(file_inc[i]))
+ }
Error in read.table(file = file, header = header, sep = sep, quote = quote,
:
object 'file_inc' not found
> sulfate <- subset(dat( , 2))
Error in subset(dat(, 2)) : could not find function "dat"
> nitrate <- subset(dat( , 3))
Error in subset(dat(, 3)) : could not find function "dat"
> mean(pollutant)
Error in mean(pollutant) : object 'pollutant' not found
> save"pollutantmean.R"
Error: unexpected string constant in " save"pollutantmean.R""
