Hi Try something like (as you have not given a reproducible example)
library(lattice) xyplot(y1 + y2+ y3 ... ~ x, data = your data.frame, type = "b", allow.multiple = TRUE) Read ?xyplot CAREFULLY as there are many possibilities you may want to have a look at library(lattice) ?useOuterStrips and other functions in the package See http://lmdvr.r-forge.r-project.org/figures/figures.html for ideas Regards Duncan Duncan Mackay Department of Agronomy and Soil Science University of New England Armidale NSW 2351 Email: home: mac...@northnet.com.au -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Waseq Ziaie Sent: Thursday, 21 August 2014 08:55 To: r-help@r-project.org Subject: [R] Line Graph greater than 2 variables on plot Hi all, I was wondering if anyone knew how to construct a multiple line graph on R, where there are 2 (or more) sets of data points plotted against some x axis of data, and you can draw a line on the graph connecting each set of data points. for example: time..years. incidence rural urban 1 2004 295.4 19.01 9.50 2 2005 824.1 19.95 9.98 3 2006 1078.0 20.70 10.35 4 2007 1258.0 21.26 10.63 5 2008 1800.0 21.83 10.91 6 2009 1890.0 18.93 9.47 7 2010 1999.0 19.41 9.71 8 2011 2261.0 19.89 9.95 9 2012 2321.0 20.28 10.14 Idea: a) I am planning plot a graph of data illustrated above where on Y-axis we can have data in sets INCIDENCE, RURAL and URBAN and on X-axis the points in set TIME..YEARS. b) Would like to be able to draw three lines ,connecting the points for each set of INCIDENCE, RURAL and URBAN over TIME..YEARS. I have tried really hard to find something but wasn't successful, the latest information I received after doing the command shown underneath was: > plot(data1$time..years.,data1$incidence,main="Plot illustrating diarrhoeal incidence over time", xlab="Time(years)",ylab="Diarrhoeal incidence",ylim=range(data[c("incidence","rural","urban")]),type"l", col=2) Error: unexpected string constant in "plot(data1$time..years.,data1$incidence,main="Plot illustrating diarrhoeal incidence over time", xlab="Time(years)",ylab="Diarrhoeal incidence",ylim=range(data[c("incidence","rural","urban")])" Many thanks, W [[alternative HTML version deleted]] ______________________________________________ R-help@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. ______________________________________________ R-help@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.
