ggplot2 in loops and multiple plots

# ggplot2 version
out <- NULL
p <- ggplot(data.frame(movieSummary), aes(y=movieSummary$Profit)) + ylab("Profits") + scale_y_continuous(labels=comma)
for(i in 2:(ncol(movieSummary)-1)) {
  p <- p + aes_string(x = names(movieSummary)[i]) + xlab(colnames(movieSummary[i])) + 
  out[[i]] <- p
  # ggsave(filename=paste("Plot of Profit versus",colnames(movieSummary[i]),".pdf",sep=" "), plot=p)
grid.arrange(out[[2]], out[[3]], out[[4]], out[[5]], out[[6]], out[[7]],
             out[[8]], nrow = 7)

Too tired to explain after so much debugging. But the key is at the line here

p + aes_string(x = names(mydata)[i])

Use aes_string instead of aes, so that when you look at summary(ggplot_obj), the mapping for x-values that are changing will be the actual string and not a variable i.
