problem with using apply for dataframe
Dear people,
I am including an example of a dataframe:
mydataframe<-data.frame(X=c(1:4),total_bill=c(16.99,10.34,21.01,23.68),tip=c(1.01,1.66,3.50,3.31),sex=c("Male","Male","Male","Female"))
When I use the sapply function getting the information about the factors
works:
sapply(mydataframe,function(x)is.factor(x))
X total_bill tip...

ggplot facet label font size
How do I change the font size in the facet labels along the edges of the
plot?
For example (from the ggplot help file):
p<-ggplot(tips, sex ~ smoker, aesthetics=list(x=tip/total_bill))
gghistogram(p)
In this plot, the facet labels are "smoker: No", "smoker: Yes", "sex:
Female", "sex: Male". What command can I use to reduce the font size of
these labels?
In lattice terminology, cex is used to scale these strip labels. But I
could...

ggplot2 axis color
Hi:
Does anyone have an idea on how to color the axis and
labels using ggplot2? This is what I got:
library(ggplot2)
p <- qplot(total_bill, tip, data = tips)
NewPlot<- p + geom_abline(slope=c(0.1,0.15,0.2),
colour=c("red","blue","yellow"),size=c(2,5,2))
NewPlot + geom_smooth(colour="green",
size=3,linetype=3)
NewPlot$background.fill<-"cornsilk"
NewPlot$background.colour <-...
