Generate data

library(ggplot2)
a <- seq(1, 20)
b <- a^0.25
df <- as.data.frame(cbind(a, b))

basic plot

myplot = ggplot(df, aes(x = a, y = b)) + geom_point()
myplot

plot of chunk ggplot-2-1

theme_bw() will get rid of the background

myplot + theme_bw()

plot of chunk ggplot-2-2

remove grid (does not remove backgroud colour and border lines)

myplot + theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank())

plot of chunk ggplot-2-3

myplot + theme(panel.border = element_blank())

plot of chunk ggplot-2-4

add axis line

myplot + theme(axis.line = element_line(colour = "black"))

put all together - method 1

myplot + theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(),
panel.background = element_blank(), axis.line = element_line(colour = "black"))

plot of chunk ggplot-2-8
