Thank you Peter. plot.default works perfectly.
I'm puzzled now with the first column of the dataframe aggr.
aggr comes from:
aggr<-summarize(child65$benvii, by=child65$decedad, FUN=mean, na.rm=TRUE)
If I write:
> aggr[,1]
[1] [65,67) 67 [68,70) [70,72) [72,74) [74,77) [77,79) [79,81) [81,84)
[84,98]
attr(,"label")
[1] child65$decedad
Levels: [65,67) 67 [68,70) [70,72) [72,74) [74,77) [77,79) [79,81) [81,84)
[84,98]
> aggr[,2]
[65,67) 67 [68,70) [70,72) [72,74) [74,77)
[77,79) [79,81) [81,84)
0.00000000 0.00000000 -0.06669137 -0.71294981 -0.59783700 -1.08334482
-1.88273125 -1.21924028 -1.94591015
[84,98]
-1.65822808
attr(,"label")
[1] "child65$benvii"
attr(,"class")
[1] "labelled" "array"
So, it's like if the first column does not exist. It does not even have a name.

Asunto: Re: [R] Lines instead of points in a scatterplot
The root cause is that column 1 is a factor. So what you get is really a set of
parallel boxplots each based on one observation.
plot.default() is one way out, but you may need to generate the x-axis labels
yourself.
I.e.,
x <- factor(LETTERS[1:10])
y <- rnorm(10)
plot(x,y)
plot.default(x,y)
For full control, recode the factor to a numeric variable.
