I am having a problem in opening the excel files in specdata folder.
I have completed coding the R program for the assignment but when I run the
following commands in the R console,
*source("pollutantmean.R")*
*> pollutantmean("specdata", "nitrate", 23)*
I get an error message stating
*Error in file(file, "rt") : cannot open the connection*
*In addition: Warning message:*
*In file(file, "rt") :*
* cannot open file 'specdata/023.csv': No such file or directory*
I tried everything and reset my Working Directory to
*C:/Users/acer/My Documents/specdata/rprog-data-specdata/specdata*
After the last specdata folder are all the excel sheets numbered 001 to 332.
I searched the internet and all other options available, and got a solution
to open it using the following command:
*df <- read.csv("specdata/001.csv")*
This generated the following error message
*Error in file(file, "rt") : cannot open the connection*
*In addition: Warning message:*
*In file(file, "rt") :*
* cannot open file 'specdata/001.csv': No such file or directory*
I have tried various other commands also such as
*path <- c(paste("./",directory, "/",formatC(id[i], width=3,
flag=0),".csv",sep=""))*
However, all the commands show some error.
What shall I do?
I am using the 3.2.1 version of R on a Windows 8 laptop.
