y-axis in histograms
Dear R- list,
I have some data to present with histograms. Therefore I used hist(...).
I have few values with almost 80% of
the frequencies (totaly 800) and some other values with low frequencies
( totaly 5 -10 )
that I want to emphasize. Therefore I want to "cut" the y-axis on 100,
but I
don't know how to deal with this.
Thanks in advance,
Michael Graber

boxplots instead of a scatterplot
Dear R list,
I am a newbie to R and programming itself, so my question may be easy to
answer for you.
I wanted to create a scatterplot and i used the following code:
par(mar=c(10, 4.1,4.1,2.1))
plot(q$location,q$points, , las=2, cex.axis=0.5,xlab="", ylab="" )
#location are character strings, there are about 70 locations
#points are numeric, there are more than 4 points for

Dear R-List,
I am very new to R and programming itself, so my question may be easy to
answer for you.
I tried a lot and read through the manuals, but I still have the
following problem:
I have 2 data-frames:
Number<-as.numeric (Number)
Name<-as.character (Name)
TAB1<-data.frame (Name,Number)
- it looks like this:-
Name Number
A 2
A 3
A 6
B 8
B 12
B 7
C 8
D 90
