ggplot2 change y-axis label to non-scientific format

Below is a kmeans implementation, plotted with ggplot2. To change the y label values (because they are large, they are automatically formatted to scientific type i.e. exponential powers of n). To ‘unpower’ the values, you need to load the scales library and add the necessary in ggplot’s scale_y_continuous.

# K-Means Cluster Analysis
m <- mplayer    # matrix type
df <- player    # dataframe type
fit <- kmeans(m, 3)                          
aggregate(m,by=list(fit$cluster),FUN=mean)   # get cluster means

# Cluster graphing
df$cluster <- factor(fit$cluster)
centers <- as.data.frame(fit$centers)

library(scales)   # needed for formatting y-axis labels to non-scientific type
ggplot(data=df, aes(x=Experience, y=Career_salary, color=cluster )) + 
  geom_point() + scale_y_continuous(labels = comma) +
  geom_point(data=centers, aes(x=Experience, y=Career_salary, color='Center')) +
  geom_point(data=centers, aes(x=Experience, y=Career_salary, color='Center'), size=52, alpha=.3, show_guide=FALSE)
