Dear All!!
I'll try to plot a barplot using aggplot2
head(alt)
as.factor.data...7.. Col ColMat Fastq miseq
1 189 158 158 158 104
2 190 54272 54272 54272 32122
3 191 301574 301574 301574 152625
4 192 161620 161620 161620 100469
5 193 61263 61263 61263 38109
6 194 83800 83800 83800 40095

p<- ggplot(data = alt, aes(y = alt[,2])) + geom_bar()
Error : Mapping a variable to y and also using stat="bin".
With stat="bin", it will attempt to set the y value to the count of cases in
each group.
This can result in unexpected behavior and will not be allowed in a future
version of ggplot2.
If you want y to represent counts of cases, use stat="bin" and don't map a
variable to y.
If you want y to represent values in the data, use stat="identity".
See ?geom_bar for examples. (Defunct; last used in version 0.9.2)
How can resolve this problem?
My data are in column: each columns are conditions and each row rappresnt a
sample
thanks for your help!
