Thank you, Petr. I understand now. I thought the first column Peter was referring to in his email was
1 10 2 3 4 5 6 7 8 9 that appears when I write > aggr. In facti, it is: [65,67) 67 [68,70) [70,72) ... There is no need to change this column if one uses plot.default Angel -----Mensaje original----- De: PIKAL Petr [mailto:petr.pi...@precheza.cz] Enviado el: vie 12/09/2014 11:40 Para: Vivek Das; Angel Rodriguez CC: R help Asunto: RE: [R] Lines instead of points in a scatterplot Hi look at str(aggr) I bet you will find that your first column is factor and lines you see are from making a boxplot with your plot command. You can change it by various ways but I would prefer to change factor to numeric, which requires some regular expression. Here is one but I believe that other experts can come with easier one. dat <- gsub("^.*([[:digit:]]{2}),([[:digit:]]*).*$", "\\1", aggr$child65$decedad) Then plot plot(dat, aggr[,2]) shall produce points. Another option can be plot(as.numeric(aggr[,1], aggr[,2], axes=FALSE) and then you need to ad axes labels, see ?axis Regards Petr > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- > project.org] On Behalf Of Vivek Das > Sent: Friday, September 12, 2014 10:50 AM > To: Angel Rodriguez > Cc: R help > Subject: Re: [R] Lines instead of points in a scatterplot > > HI, > > Try to change with > > plot(aggr, type="l") > > see what happens? > > This should work > > ---------------------------------------------------------- > > Vivek Das > > > On Fri, Sep 12, 2014 at 10:32 AM, Angel Rodriguez < > angel.rodrig...@matiainstituto.net> wrote: > > > > > > > Dear subscribers, > > > > I have the following dataframe: > > > > > aggr > > child65$decedad logit > > 1 [65,67) 0.00000000 > > 10 67 0.00000000 > > 2 [68,70) -0.06669137 > > 3 [70,72) -0.71294981 > > 4 [72,74) -0.59783700 > > 5 [74,77) -1.08334482 > > 6 [77,79) -1.88273125 > > 7 [79,81) -1.21924028 > > 8 [81,84) -1.94591015 > > 9 [84,98] -1.65822808 > > > > When I write: > > > > > plot(aggr) > > > > I get the correct scatterplot, but points are substituted by > > horizontal lines.
