Hello,

There are many typos in your call to read.csv.
This should be the right way to read in the data.


g <- read.csv("cancer_data.csv", header = TRUE, sep = ',')


Try running


help("read.csv")


and see the correct way of calling read.csv and other similar functions.
You will find that read.table is the general purpose function to read 
tabular data, read.csv is a special case with some frequent defaults 
already set, including header=TRUE and sep=",". So, you can simply run


g <- read.csv("cancer_data.csv")   # header=TRUE and sep="," already set


hope this helps,
