Hello all,
I have a large data frame and I want to look at the distribution of each variable very quickly by plotting an individual histogram for each variable.
I'd like to do so using lattice.
Here is a small example using the iris data set:
histogram(as.formula(paste("~",paste(colnames(iris[,!sapply(iris,is.factor)]),collapse="+"))),data=iris[,!sapply(iris,is.factor)])
However in this graphic, the x-axis and the breaks are the same for all 4 variables. I would like them to be adjusted to the data in each panel separately. I have tried using the scales argument to no avail:
histogram( as.formula(paste("~",paste(colnames(iris[,!sapply(iris,is.factor)]),collapse="+"))) ,data=iris[,!sapply(iris,is.factor)], scales=list(x=list(relation="free")) )
How can I individualize the x-axis and breaks for each individual panel?
Thanks for any help.
