I am trying to make some plots for a poster. Each one needs to be 6 inches by inches. Right now the fonts are too small and the plots don't read well on my poster. I am pretty much an R newbie and I can't figure out how to change the fonts. It would also be nice to know how to specify the size of the plot and maybe how to save the plots as jpeg files. Any help would be much appreciated! I am not too picky about the details like font type, I just want the size of the fonts (especially the axes and axes labels) to be bigger!
Thanks so much! Here is my code: # Poster figure 1 stationmean=c(19.4833,10.8000) fieldmean=c(14.6852, 15.5981) plot(c(0,1),fieldmean,xaxt='n',type="b",pch=20,col="green3", main="Foxtail Seeds Remaining vs.Field Type", ylab="Mean Number Foxtail Seeds Remaining", xlab="Field Type",ylim=c(10,20),xlim=c(-.25,1.25)) axis(1,at=c(0,1),labels=c("Cover Crop","Wheat Stubble")) # Poster figure 2 stationmean=c(19.4833,10.8000) fieldmean=c(14.6852, 15.5981) plot(c(0,1),stationmean,xaxt='n',type="b",pch=20,col="green3", main="Foxtail Seeds Remaining vs. Station Type", ylab="Mean Number Foxtail Seeds Remaining", xlab="Station Type",ylim=c(10,20),xlim=c(-.25,1.25)) axis(1,at=c(0,1),labels=c("Invertebrate Only","Open Access")) # Poster figure 3 meantime=22.1 meancumrainfall=.4837 meanavelowt=35.4920071 meanavehight=55.3242738 meanvegcover=81.1729167 pred.veg = 33.3160 + -.2439*meantime - .8409*(.5) + 8.6833*(.5) + .5427*(meancumrainfall)-.3087*(meanavehight) + .01087*(seq(0,164.5,by=5)) pred.veg plot(seq(0,164.5,by=5),pred.veg,type='l',col='blue',lwd=2, main='Foxtail Seeds Remaining vs. Vegetative Cover Biomass', xlab='Vegetative Cover Biomass (g / 0.25 m^2', ylab='Mean Number Foxtail Seeds Remaining',ylim=c(10,22)) # Poster figure 4 meantime=22.1 meancumrainfall=.4837 meanavelowt=35.4920071 meanavehight=55.3242738 meanvegcover=81.1729167 pred.rain = 33.3160 + -0.2439*meantime - .8409*(.5) + 8.6833*(.5) - 1.0571*(seq(0,1.569,by=.1))-.3087*(meanavehight) + .01087*(meanvegcover) pred.rain plot(seq(0,1.569,by=.1),pred.rain,type='l',col='blue',lwd=2, main='Foxtail Seeds Remaining vs. Cumulative Rainfall', xlab='Cumulative Rainfall (in)', ylab='Mean Number Foxtail Seeds Remaining',ylim=c(10,22)) # Poster figure 5 meantime=22.1 meancumrainfall=.4837 meanavelowt=35.4920071 meanavehight=55.3242738 meanvegcover=81.1729167 pred.high = 33.3160 + -.2439*meantime - .8409*(.5) + 8.6833*(.5) + 1.0571*(meancumrainfall)-.3087*(seq(37.733,74.38228571,by=1)) + .01087*(meanvegcover) pred.high plot(seq(37.733,74.38228571,by=1),pred.high,type='l',col='blue',lwd=2, main='Foxtail Seeds Remaining vs. Average Daily High Temp', xlab='Average Daily High Temperature (degrees F)', ylab='Mean Number Foxtail Seeds Remaining',ylim=c(10,22)) # Poster figure 6 meantime=25.3333333 meancumrainfall=.4015 meanavelowt=37.9325 meanavehight=62.2579683 meanvegcover=77.6145833 meannumtotseedwt=.8708333 pred.seed = 24.4096 + -.1930*meantime - 3.5233*(.5) + 11.8611*(.5) - 2.7335*(meancumrainfall)-.1510*(meanavehight) + .01286*(meanvegcover) - 3.2848*(seq(.2,1.6,by=.05)) pred.seed plot(seq(.2,1.6,by=.05),pred.seed,type='l',col='blue',lwd=2, main='Foxtail Seeds Remaining vs. Ambient Seed Load', xlab='Ambient Seed Load (g / 0.25 m^2', ylab='Mean Number Foxtail Seeds Remaining',ylim=c(8,16)) -- View this message in context: http://r.789695.n4.nabble.com/Easy-help-with-plots-font-size-tp3259270p3259270.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
