Using this data: skittle-data.csv (Every row was an individual bag of skittles submitted by each student)
I'm trying to generate some charts and other things to satisfy the assignment. While doing so, I noticed that in determining the total number of skittles I was off by 1.
When I load the csv into a dataframe I make summations of the rows, and then sum those summations to get the total, like this:
skittles = read.csv("skittle-data.csv", header = TRUE)
columnTotals = colSums(skittles, na.rm=FALSE, dims = 1)
rowTotals = rowSums(skittles, na.rm=FALSE, dims = 1)
total = sum(rowTotals, na.rm=FALSE, dims = 1)

Here's what I am doing :sc.textFile('file.csv') .map(lambda line: (line.split(','), line.split(','))) .collect()I would expect this call to give me a list of the two first columns of my file but I'm getting this error :File "", line 1, in IndexError: list index out of rangealthough my CSV file as more than one column.
