Dear r-help members.
I would like to:
a) control the margin around my legend box. Unfortunately I did not find an
appropriate command under "?legend". The margin around the actual legend is way
too wide. There is a lot of unnecessary "empty space" on the right side.
b) increase the width of the individual barplots. I saw that this can be
obtained with the command "width" and "xlim".However, since I have 3 Barplots
next to each other "beside=T", I could not figure it out how to do it (2
Barplots are disappearing)
c) I wanted to label each bar ("names.arg") unfortunately nothing happens if I
use this command (in my code i just used 1:10 for the names, in the original
plot I would replace the numbers with real names)
Thank you very much:
Input data (dput)
structure(list(total = c(28L, 17L, 11L, 6L, 6L, 5L, 4L, 3L, 3L,
2L), young = c(29L, 22L, 15L, 8L, 5L, 3L, 2L, 2L, 2L, 2L), old = c(36L,
11L, 11L, 8L, 6L, 5L, 4L, 3L, 2L, 2L)), .Names = c("total", "young",
"old"), class = "data.frame", row.names = c(NA, -10L))
R-code:
barplot(as.matrix(plants_herbs_input_top10),xaxt="n",
space=c(0.5,12),ylab= "Relative frequencies (%)",beside=TRUE,
col=c(rep("black",10),rep("chartreuse1",10),rep("chartreuse4",10)),ylim=c(0,50),cex.names=0.8,names.arg=c("1",
"2", "3","4","5","6","7","8","9","10","1", "2",
"3","4","5","6","7","8","9","10","1", "2", "3","4","5","6","7","8","9","10"))
legend("topright",c("Total","Young secondary forest","Old secondary
forest"),cex=0.9,pt.cex=1,y.intersp=0.4,pch=15,col=c("black","chartreuse1","chartreuse4"))
