Make sure that the file 'CaptaincyData.csv' is stored in your working directory. Check your current working directory using the command 'getwd()' and then check if 'CaptaincyData.csv' is stored there or not. It seems from the above messages that 'CaptaincyData.csv' is not present in your working directory.
