bug in qplot (library ggplot2)
Dear Pierre,
A more elegant solution is to use ggsave()
library(ggplot2)
for (i in 1:2) {
p <-
qplot(carat, data=diamonds, fill=color,geom='histogram')+scale_y_continuous(i)
ggsave(filename = paste('test ',i,'.png',sep=''), plot = p)
}
Best regards,
Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The corrected code:
library(ggplot2)
for (i in 1:2) {
png(file=paste('test ',i,'.png',sep=''))
print(qplot(carat, data=diamonds,
fill=color,geom='histogram')+scale_y_continuous(i))
dev.off()
}
Thanks

Hello,
this following code give a nice png:
/library(ggplot2)
i<- 1
png(file=paste('test ',i,'.png',sep='')) qplot(carat, data=diamonds,
fill=color,geom='histogram')+scale_y_continuous(i)
dev.off()
/
I would like to get more files, but the following code doesn't make
any
file:
/library(ggplot2)
for (i in 1:2) {
png(file=paste('test ',i,'.png',sep=''))
qplot(carat, data=diamonds,
fill=color,geom='histogram')+scale_y_continuous(i)
dev.off()
}
/
Have you got any idea?
Have I made something false?
Thanks,
Pierre-Olivier
