[R] Help with marmap package
Hello, I'm using the 'Marmap' R package to create ocean bathymetry maps. I've managed quite well, but I'm having a little difficulty with setting my x-axis (longitude) limits. When I run the code, the map is projected with large white bands on either side of the desired longitude limits. I've tried setting the limits myself (i.e xlim = c(115, 130)). I've also tried setting the 'xaxs' parameter to 'i', with no luck. I've included the code below, with the NOAA bathymetry data I'm trying to map. If anyone has had any experience with this package and has encountered similar problems and has a solution, I'd love to hear about it. # Load package library(marmap) # Import bathymetry bat <- getNOAA.bathy(130, 115, -26, -12, res = 1, keep = TRUE) # Plot map with isobaths every 1000m plot(bat, image = TRUE, land = TRUE, deep=-1, shallow=-1000, step=1000, drawlabels = TRUE, bpal = list(c(min(bat,na.rm=TRUE), 0, blues), c(0, max(bat, na.rm=TRUE), greenbrowns)), lwd = 0.1, col = 'grey20') Regards, Jake Andrae PhD Candidate Geology & Geophysics � Sprigg Geobiology Centre Department of Earth Science School of Physical Sciences The University of Adelaide, AUSTRALIA 5005 Phone: 0407701565 Email: jake.and...@adelaide.edu.au [[alternative HTML version deleted]] __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
Re: [R] Superscript in graph text
Thank you, your suggestions are very helpful. As I said, I'm a novice to R and
this list, and it's hard for me to decipher exactly what is required; I was
really hoping for some basic script formatting guidance (which was given and
appreciated).

your example is not reproducible because I don't have your dataset.
Please re-read the notes
at the bottom of every R-help email
PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.
The convention on this email list is to always stay on the list. It
is not good form to
write only to the person who replies to you and the list.
For base graphics, you can use an expression or bquote in any of the
annotation arguments or functions.
I showed you a use in main=. It works the same for all others.
plot(1:10)
p <- .4
R2 <- .9876
mtext(bquote(p * " = " * .(p)), adj=0, line=0.1, col="black", cex=0.7)
mtext(bquote(R^2 * " =" * .(R2)), adj=0, line=1, col="black", cex=0.7)
## Using mtext doesn't look like a good idea.
## use sub or main or some other keywords
title(main=bquote(p * " = " * .(p)),
sub=bquote(R^2 * "/" * p * " = " * .(R2/p)))
## Or do it all together
p <- .4
R2 <- .9876
plot(1:10,
main=bquote(p * " = " * .(p)),
sub=bquote(R^2 * "/" * p * " = " * .(R2/p)),
xlab=bquote(R^2 * " = " * .(R2)),
ylab=expression(e^(-z^2))
)
## at some point, soon I recommend, you should learn either lattice or ggplot.
## you might also want to look at the archives of R-SIG-Geo,start with
https://www.r-project.org/mail.html
## Please Keep the list in further emails

[R] Superscript in graph text
Hello,
I've added some statistical information as text to some graphs, but I'm having
a really hard time making the 2 in the R2 label superscript. Does anyone have
any suggestions?
mtext(paste("R2 = ", R2), adj=0, line=1, col="black", cex=0.7)

[R] Adding regression line to each individual plot in a window with multiple plots
Hi Everyone, I've constructed a script that adds multiple plots to the plot window, but I'm having a bit of trouble adding a regression line to each individual plot. Of course, the regression lines will vary depending on the variables plotted against one another. I've attached the script. #Growing season #Construction of plots # 12 figures arranged in 3 rows and 4 columns attach(mtcars) par(mfrow=c(3,4), mar = c(.6,.5,.6,1), oma = c(15,4,2,2), xpd = NA) #Concentration plot(Growing_season_precipitation, Concentration, xaxs = "i", yaxs = "i", xlim = c(0, 700), ylim = c(0,500), xlab = NA, ylab = "Concentration", xaxt='n', pch=21, bg='black', abline(lm(Growing_season_precipitation~Concentration))) plot(Growing_season_VPD, Concentration, xaxs = "i", yaxs = "i", xlim = c(0.6, 1.8), ylim = c(0,500), xlab = NA, ylab = "", xaxt='n', pch=21, bg='black', yaxt='n') plot(Growing_season_Rhmax, Concentration, xaxs = "i", yaxs = "i", xlim = c(35, 60), ylim = c(0,500), xlab = NA, ylab = "", xaxt='n', pch=21, bg='black', yaxt='n') plot(Growing_season_temperature, Concentration, xaxs = "i", yaxs = "i", xlim = c(20,34), ylim = c(0,500), xlab = NA, ylab = "", xaxt='n', pch=21, bg='black', yaxt='n') #ACL plot(Growing_season_precipitation, ACLTotal, xaxs = "i", yaxs = "i", xlim = c(0, 700), ylim = c(28,32), xlab = "", ylab = "ACL", xaxt='n', pch=21, bg='black') plot(Growing_season_VPD, ACLTotal, xaxs = "i", yaxs = "i", xlim = c(0.6, 1.8), ylim = c(28,32), xlab = "", ylab = "", xaxt='n', pch=21, bg='black', yaxt='n') plot(Growing_season_Rhmax, ACLTotal, xaxs = "i", yaxs = "i", xlim = c(35, 60), ylim = c(28,32), xlab = "", ylab = "", xaxt='n', pch=21, bg='black', yaxt='n') plot(Growing_season_temperature, ACLTotal, xaxs = "i", yaxs = "i", xlim = c(20,34), ylim = c(28,32), xlab = "", ylab = "", xaxt='n', pch=21, bg='black', yaxt='n') #CPI plot(Growing_season_precipitation, CPITotal, xaxs = "i", yaxs = "i", xlim = c(0, 700), ylim = c(0,30), xlab = "Total precipitation (mm)", ylab = "CPI", pch=21, bg='black') plot(Growing_season_VPD, CPITotal, xaxs = "i", yaxs = "i", xlim = c(0.6, 1.8), ylim = c(0,30), xlab = "Average daily VPD (kpa)", ylab = "", pch=21, bg='black', yaxt='n') plot(Growing_season_Rhmax, CPITotal, xaxs = "i", yaxs = "i", xlim = c(35, 60), ylim = c(0,30), xlab = "Average daily RHmax (%)", ylab = "", pch=21, bg='black', yaxt='n') plot(Growing_season_temperature, CPITotal, xaxs = "i", yaxs = "i", xlim = c(20,34), ylim = c(0,30), xlab = "Average daily temperature (oC)", ylab = "", pch=21, bg='black', yaxt='n') #Plot main title title(main="Growing season (June-November, inclusive)",outer=T) Any help would be greatly appreciated!

[R] Colour gradients in ggtern
Hello, This is my first time posting to the r-help mailing list and I'm a relative amateur using R, so forgive my naivety. I am constructing a ternary diagram using the ggtern extension of the ggplot package, and I'm having some trouble with the colour gradient I want it to display. I have attached the output plot, where a rainbow colour gradient can be seen, but I really need these colours to be in reverse order. This is the command I used to construct the plot; #Plot construction > ggtern(data= C27_C29_C31, aes(x=C27,y=C29,z=C31))+geom_point(aes(colour= > GST),size=3)+theme_light()+theme_nogrid_minor()+scale_colour_gradientn(colours > = rainbow(5.5)) Is there a simple way to reverse the colours in the scale_colour_gradientn command?
