That is likely?because?ferm is a factor. ?A scatterplot is two numeric variables. ?To make it a scatterplot wrap ferm with as.numeric.? Cheers, Tyler ---------------------------------------- Date: Mon, 14 May 2012 12:21:12 -0700 From: kellycool79 at yahoo.com To: r-help at r-project.org Subject: [R] Plot Hello, I am trying to make a plot of the rates of an enzyme against three different protein concentrations (there are 45 rates in total and split up into 3 groups of 15, each receiving one of the 3 protein concentrations). When I enter the following code I instead get 3 separate boxplots for each of the three different protein concentrations ... plot(rate ~ ferm, data=LDH, col=LDH$rate, pch=c(17,18,19)[(as.numeric(LDH$rate)%%3)+1]) but I want a scatterplot showing 3 different lines indicating each of the protein concentrations. I'm not sure if I need to tweak my data set in order to get what I want? I was also wondering how to include the origin (0,0) in the plots. I'm not sure if I'm missing something on the plot help page? Any help would be appreciated. Thanks so much. ______________________________________________ R-help at r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
I noticed I was remiss in?addressing?your origin question: Use the xlim and ylim, setting the lower limit to 0. ?Here's an example of this with the CO2 dataset: plot(uptake~Plant, data=CO2) plot(uptake~as.numeric(Plant), data=CO2) plot(uptake~as.numeric(Plant), data=CO2, ylim=c(0, 50), xlim=c(0, 14)) Cheers,Tyler ----------------------------------------
