Error in rename.default(x, .base_to_ggplot) : object '.data' not found -- ???????

[dzroth]

Hello,

I'm new to ggplot2, but from what i've seen, it looks like a great
program. However I'm having some difficulties using the package. I'm
attempting to create a bar plot showing the number of individuals in
each species across a series of sites. However, no matter how I
attempt to set up the script, I get the following error message.


"Error in rename.default(x, .base_to_ggplot) : object '.data' not
found"

This error message appears to be popping up even on scripts which
successfully produced nice figures yesterday. I'm guessing it has to
do with my data structure (see below), but I can't for the life of me
figure it out.

Any information anyone may have would be greatly appreciated.

Thanks,

Dave

Hi Dave, I don't know what your problem is as I don't know what code are you using. However I have no problems using this code, I'm assuming the traps number are the locations

#mosquitos is the data you supplied

library(ggplot2)

qplot(Species, Number, data = mosquitos, fill = as.factor(Trap), geom = 'bar', position = 'dodge' )
#The graph doesn't look well as the labels of the species overlap, so we add this

last_plot() + opts ( axis.text.x = theme_text (angle = 45, vjust = 1 , hjust = 1 ) )

#if you want the location on the x axis the code is

qplot(as.factor(Trap), Number, data = mosquitos, fill = Species, geom = 'bar', position = 'dodge' )

#if you just want the stacked bars, then remove the "position = 'dodge'" bit

qplot(as.factor(Trap), Number, data = mosquitos, fill = Species, geom = 'bar'

I hope that's what you wanted

Bye and good luck with the code
