[R] y-axis-problem (barplots)

2012-05-07 Thread David Studer
Hi everybody!

I would like to plot a barplot, but, unfortunately, when I change the
y-axis limits
the bars do not start at 0 any more but get negative:

#
# Data (just a short example):

a-c(1.61, 2.1)
b-c(1.5, 1.9)
c-c(1.85, 2.2)
d-c(1.63, 2.3)

x-rbind(a,b,c,d)
colnames(x)-c(var1,var2)

# Problem:

barplot(x[,1])
barplot(x[,1], ylim=c(1,2))  # Bars do not start at 0
#

Could anyone help me? Thank you!

David

Does this do what you want

barplot(x[,1], ylim=c(1,3), offset=1)

And if the y-axis starts with 0: Instead of ylim=c(1,2), you take ylim=c(0,2). 
Thus barplot(x[,1], ylim=c(0,2)) Hopefully it is now correct.  Kind
