Changing x-axis tick colour in a ggplot

I'm trying to change the colour of the X.axis tick colour to Black, as described here: https://github.com/hadley/ggplot2/wiki/Axis-Attributes#axistextx-text
However when I run my code I'm getting the error message:
Error: could not find function "theme"

ggplot(long.repmixed.df, aes(x = log10intensity, colour = channel, fill = channel)) +
geom_bar(position="dodge") +
theme(axis.text.x = element_text(colour = "black")) +
opts(panel.background = theme_rect(fill = 'white', colour = 'black')) +
opts(panel.grid.major = none, panel.grid.minor = none)

I'm basically trying to plot a histogram with no grid and white BG. Can anybody rectify the problem please.

It looks like you can either update your version of ggplots or use the 'old' way of changing the text color. opts(axis.text.x = theme_text(colour="black"), axis.text.y = theme_text(colour="black"))

The correct syntax should be theme(axis.text.x = element_text(colour="black"), axis.text.y = element_text(colour="black")).
