save multiple within a loop using ggsave

[Matthias]

We are trying to create and save multipe plots using ggplot (ggsave).

Here is an example of the problem we are currently not able to manage:

name<-c("a","b","c","d")
value<-1:4

dataframe<-data.frame(name,value)

leader<-max(dataframe$value)
meanvalue<-mean(dataframe$value)

for (i in 1:4) {

Index<-dataframe$value[i]

x<-c("leader", "meanvalue", dataframe$name[i])
y<-c(leader, meanvalue,Index)
plotframe<-data.frame(x,y)

z<-ggplot(plotframe, aes(x,y))+ geom_bar()

}



We want to plot each value for all 4 names compared to the mean and
the leader. We would like to get 4 plots to be saved in 4 different
files. We have tried savePlot, but it did not work.

Thanks in advance,

Matthias

Something like this should work...

for (i in 1:4) {

Index<-dataframe$value[i]

x<-c("leader", "meanvalue", dataframe$name[i])

y<-c(leader, meanvalue,Index)

plotframe<-data.frame(x,y)

z<-ggplot(plotframe, aes(x,y))+ geom_bar()

ggsave(sprintf("barplot.%s.png", i), width=6, height=6)

}
