Hi,
I try to make a selective plot, but it make an error. The subset only work
with length < 4, it is correct?
>
plot((ocorrencia/isca)~frag,subset=especieama==c("grupo1","grupo2","grupo3","AnoplotermesSp1","NeocapritermesOpacus"),pch=c(1,2,3,4,5),xlab="�rea
(ha)",ylab="Propor��o de iscas ocupadas por t�rmitas")
Warning messages:
1: longer object length
is not a multiple of shorter object length in: is.na(e1) | is.na(e2)
2: longer object length
is not a multiple of shorter object length in: "==.default"(especieama,
c("grupo1", "grupo2", "grupo3", "AnoplotermesSp1",
I make the plot using points, but I want to know if this is a bug or real
limitation in subset comparison.
I use R-1.7.1
Thanks
Ronaldo
