Hey,
Is it possible that R can calculate each options under each column and
return a summary table?
Suppose I have a table like this:
Gender Age Rate
Female 0-10 Good
Male 0-10 Good
Female 11-20 Bad
Male 11-20 Bad
Male>20 N/A
I want to have a summary table including the information that how many
answers in each category, sth like this:
X Gender
Male 3
Female 2
N/A 0
X Age
0-10 2
11-20 2
20 1
N/A 0
X Rate
Good 2
Bad 2
N/A 1
So basically I want to calculate, in each column, how many people choose
each answer, including N/A. I know I can do it in Excel in a very
visualized way, but is there anyway to do it in R in a robust way if I have
a fairly large dataset.
Hey Ye,
How about this?
yldat<-read.table(text="Gender Age Rate
Female 0-10 Good
Male 0-10 Good
Female 11-20 Bad
Male 11-20 Bad
Male >20 N/A",header=TRUE)
require(prettyR)
describe(yldat)
Jim
