Hi ,
I am having serious trouble doing this homework. I am using R for doing the
homework. I am having the following specific problem:
a) when I input the data using the command > Wbdc <-read.table("wdbc.txt") I
do not see the data.
b) When I want to run histogram using command > hist(area) I get an error
message,
Error in hist(area) : object "area" not found.
I am attaching the data file I imported to R and a screenshot of the workspace.
Please help.
Thanking you
