Dear Rxperts..
what settings in barplot and histogram do I use, to show bars in an
monotonously increasing or decreasing order of the frequency of a
categorical variable?
an example is provided below..
histogram(~factor(sample(letters,200,rep=T)))
I was able to get it in 3 - 4 steps.. l
a1 <- sample(letter,200,rep=T)
a2 <- table(a1)
barplot(a2); barplot(sort(a2)) # all variables are not displayed on the
x-axis in the barplot
histogram(factor(a1)) # the resulting bars are not shown in seqentially
increasing or decreasing order
how do I use similar plots if I have data.frame...
example is shown below..
b1 <- data.frame(lets=sample(letters,200,rep=T),n=seq(200))
barplot(sort(table(b1$lets))
histogram(b1$lets)
Regards,
Santosh
