Graphical Display of Values' Distribution
I have a column within a dataframe of values which range between 1 and 2. I want to display graphically the distribution of these values (i.e. are they clustered towards either exteme? Or spread evenly?). What is a good way of doing this in R? I've tried a few things, including using the 'hist' command, but receive the following error message:
hist(urban.long[3])
Error in hist.default(urban.long[3]) : 'x' must be numeric ...which is strange because all the values *are* numeric!
Your approach is correct with one minor glitch: urban.long[3] is not a vector but again a data.frame. Try hist(urban.long[,3]) That should do what you want. cu Philipp
