Turning pass/fail results into a proportion
...ns the proportions of pass/fails per variable.
So, for example:
df <- data.frame( Var=c(3,3,3,4,4),
Result=c("pass","fail","fail","pass","pass"), SampleSize=c(3,3,3,2,2))
And I'd like to produce the equivalent of:
data.frame( Var=c(3,4), ProportionPass=c(0.33, 1) )
I have found the table() function:
table( df$Var, df$Result)
which potentially seems to be part of the solution, however it turns the
Var column into factors.
As an aside, is the storage of SampleSize (above) the best technique?
Or is it better to store it in a data frame of its...
