ggplot2, qplot, problems

Dear the R Community,

I just encountered an error while using ggplot2 and the qplot function
(please see below for the warnings and error), and i have no idea about how
to make changes so that it will work.
Could anyone kindly advise me a bit and help me out here?

------------------------------------------------------------------------------------------------------

library(ggplot2)

Warning message:
package ?ggplot2? was built under R version 3.2.5

library(ggplot2)
dodge <- position_dodge(width = .9)
plot <- qplot(happening, target.looking_M, data=d.c2.subjects,

stat="identity",
+ geom="bar", position=dodge,
+ ylab="Proportion of looks", xlab="happening",
+ fill=happening, colour=happening,
+ main="Proportion target looking by condition and testing phase for each
single subject")

Warning messages:
1: `stat` is deprecated
2: `position` is deprecated

plot <- plot + facet_grid(type ~ subjectname)
plot

Error: stat_count() must not be used with a y aesthetic.

thank you very much.

Cheers,
Daniel
