Re: [R] Scatter plot / LOESS, or LOWESS for more than one parameter

First let me say thank you for all the help everyone gave me. Below is the code I came up with to look at Rainfall pH reading for Kentucky and Tennessee. Also there is a more *generic* ver of the code on my web page if anybody ever needs it in the future.

You can also use range( MC.pH, MV.pH, na.rm=TRUE). On Tue, Apr 24, 2012 at 1:29 PM, David Doyle kydaviddo...@gmail.com wrote: Hi Greg, Sloved my own problem. I had some missing data NA in the datasets.  So I manually entered the ylim=range(4,6) and it worked!!! Thanks!! David On Tue,

Re: [R] Scatter plot / LOESS, or LOWESS for more than one parameter

Assuming that you want event as the x-axis (horizontal) you can do something like (untested without reproducible data): par(mfrow=c(2,1)) scatter.smooth( event, pH1 ) scatter.smooth( event, pH2 ) or plot( event, pH1, ylim=range(pH1,pH2) , col='blue') points( event, pH2, col='green' ) lines(

Hi Michael, What I run into is that I have a lot of time-series data from groundwater wells but when plot it..it becomes way to busy to see what is going on. For example, here is the code to load and plot my Mammoth Cave rainfall pH data #Load data from web page data -

Re: [R] Scatter plot / LOESS, or LOWESS for more than one parameter

Hi Greg, Thanks, I got the 1st example to work using the following code: data - read.csv(http://doylesdartden.com/Monthly-pH-example.csv;, sep=,) attach(data) par(mfrow=c(2,1)) scatter.smooth( Year, MC.pH ) scatter.smooth( Year, MV.pH ) This is good but what I'm really looking for is to

[R] Scatter plot / LOESS, or LOWESS for more than one parameter

Hi folks. If I have the following in my data eventpH1pH2 14.0 6.0 24.3 5.9 34.1 6.1 44.0 5.9 and on and on. for about 400 events Is there a way I can get R to plot event vs. pH1 and event vs. pH2 and then do a loess or

Re: [R] Scatter plot / LOESS, or LOWESS for more than one parameter

The scatter plot is easy: plot(pH1 ~ pH2, data = OBJ) When you say a loess for each -- how do you break them up? Are there repeat values for pH1? If so, this might be hard to do in base graphics, but ggplot2 would make it easy: library(ggplot2) ggplot(OBJ, aes(x = pH1, y = pH2)) + geom_point()
