What is the easiest way to turn a dataframe into a barplot?
If you want to stay with vertical bars, the barp() function in package plotrix lets you stagger or rotate the labels:
set.seed(42)
Name=c("One","Two", "Three","Four", "Five", "Six", "Seven",
+ "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen", + "Fourteen", "Fifteen")
Count=sample.int(15, 15, replace=TRUE) z <- data.frame(Name, Count) with(z, barp(Count, names=Name)) # Some labels suppressed by the plot device
# Note that if you drag the plot window to be wider, the labels will eventually appear
with(z, barp(Count, names=Name, staxx=TRUE)) # Stagger the labels with(z, barp(Count, names=Name, staxx=TRUE, srt=60)) # Slant the labels

Ok, the horizontal names work here. Thanks.

Does this do what you want?
z <- data.frame(Name=c("One","Three","Twelve","Eleven"), Count=c(1,3,12,11))
with(z, barplot(Count, names=Name, horiz=TRUE))
with(z, barplot(Count, names=Name, horiz=TRUE, las=1))

But basically, I have a dataframe that has two columns, one is a string and the other is an integer. I want to turn this into a vertival barplot where on the x-axis I have the string in the first columb and then the plot will display the integer count. I have found many examples online and most of those matched either odd edge cases or putting the data into a format that strips out some of the data and I can't use it later. This should be a breeze, what am I missing?
