ggplot's aes_ doesn't work as expected for x=factor()
...riable names on the fly. Using aes_ doesn't work as I expected when x = factor(x). Is this a bug or am I not understanding something?
# toy dataset
df <- data.frame(LogicalVar = c(FALSE, TRUE, FALSE, TRUE, FALSE, TRUE),
Var1 = c(0.01, 0.01, 1, 1, 30, 30),
pct1 = c(12, 88, 60, 40, 93, 7),
Var2 = c(2, 2, 4, 4, 8, 8),
pct2 = c(43, 57, 10, 90, 50, 50)
)
varnames <- names(df)
# using aes()--this works
ggplot(df, aes(x=factor(Var1), y=pct1, fill=LogicalVar)) + geom_bar(stat="identity") # works

Pseudo R^2 for logit - really naive question
I am using GLM to calculate logit models based on cross-sectional data. I
am now down to the hard work of making the results intelligible to very
average readers. Is there any way to calculate a psuedo analoque to the R^2
in standard linear regression for use as a purely descriptive statistic of
goodness of fit? Most of the readers of my report will be vaguely familiar
and more comfortable with
