R help - Mar 2015 - Installed R to Windows, but having trouble with read.csv

I copied the file into the bin folder of R ...


> perf_data <- read.csv("PerfResultsCSv.csv")
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open file 'PerfResultsCSv.csv': No such file or directory

I also installed and load RWeka package, but canot open.



It seems like I am having some issue of directories...

I am new to R, any help appreciated.

Thanks,

Alice

Is this file in your working directory? (To know your working directory
use: getwd()   )

If not, put it in there.

Setting the filename using the file.choose() function is usually
easiest.  I.e.

f <- file.choose()
perf_data <- read.csv(f)

You'll get the usual file choose dialog (at least in Windows and OSX;
not sure about Linux) when file.choose() runs and can navigate to the
file.  The full name including path will be saved in f.
