Change grey background color

[Rodrigo Tardin]

Dear list,

I am new to ggplot and I am having trouble to change the grey background color of the ggplot2 default plot. I run a Spatial Eigenvector Mapping GLM to understand what environmental variables influence whales distribution in Rio de Janeiro, Brazil.

I have the following code that I used to plot:

ggplot(bryde3, aes(x = SLOPE, y = c1$neo.pred,)) + 

   stat_smooth(method = "glm", family = "binomial", se = TRUE) +

   labs( x = "Slope(m)",

        y = "Occurrence of whales")

# bryde 3 is my dataset

# SLOPE is one of my environmental variables

# c1$neo.pred <- predict(glmerr12, type = "response", se.fit = FALSE)

#glmerr12 is my GLM model

The resulting plot has a grey background and white lines.

Can anyone help me?

Thanks in advance,

Rodrigo

Dear Rodrigo,
You can also learn (a lot!) from ggplot2 help for "theme":

http://docs.ggplot2.org/current/theme.html
