Re: geom_histogram

[Brandon Hurr]

For a histogram you only supply an x variable. 

ggplot(z, aes(x=value, fill=variable)) + geom_histogram(position=position_dodge())

Hello,

 

I have applied the code, which you had sent to Sarita, to my data for a smilar plot I am interested in. I got the following error message.

 

“X=agedth” is a continuous variable that has values ranging from 18 to 95. “Fill=percent” has data that correspond to x.

 

Any help will be appreciated.

 

Thanks,

 

Pradip

stat_bin: binwidth defaulted to range/30. Use 'binwidth = x' to adjust this.

Error in unit(tic_pos.c, "mm") : 'x' and 'units' must have length > 0
