R：绘图，结果为“ plot.new尚未被调用”

Question

Data (an abridged version):

m1 1
m2 2
m3 3
m4 0
m5 32
m6 12
m7 42
m8 56
m9 29

Note: 0 is supposed to represent a space in my graph

Code:

barplot(
  name,
  main="Mike vs. Ike" , 
  ylab="Number of criminal offences of two different people" , 
  xlab="" , 
  col=c("yellow" , "blue" ) , 
  beside=TRUE , 
  ylim= range(0 , 10) ,  
  las=2 , 
  axes=TRUE ,


   names.arg = c("Mike: number of offences in: 1 day"      , 
                    "Ike: number of offences in: 1 day"     ,
                    ""                       , 
                    "Mike: number of offences in: 1 week"      ,
                    "Ike: number of offences in: 1 week"     , 
                        ""                       ,
                        "Mike: number of offences in: 1 month"        ,
                        "Ike: number of offences in: 1 month"       , 
                        ""                       ,
                        "Mike: number of offences in: 1 year"     ,
                        "Mike: number of offences in: 1 year"   


           ) ,
             legend(
  "topright" , 
  c("Mike" , "Ike") , 
  col=c("yellow" , "green") , 
  pch=c(22:22) ,
  cex=0.75 )
)  

Error I get:

Error in strwidth(legend, units = "user", cex = cex, font = text.font) : 
  plot.new has not been called yet

Billion $ question:

How can I scale my names.arg and legend to fit my graph

Danke in advance

Answer 1

I think your problem is that you're calling legend() inside your call to boxplot() whereas it's supposed to be called after . At least that's what's giving you the error. I'm not sure exactly what you mean by "scaling" the legend or names however.
