Hi List,

I would appreciate any suggestion on how can I make a text I’ve inserted in
a plot show some contrast? With this I mean that I have a white text on a
plot and I would like to make a tiny border around it in black, so even
being small sized and the entire graphic being small in the text page I’ll
insert it. It will be visible.

 

Well I tried inserting a box() function inside the text() function, R
accepts the command but there is no effect. I even tried to plot a greater
black text and then a smaller white one at the same place, but it doesn’t
look good.

 

Any ideas!

 

Bellow is my plot code without the above mentioned attempts. I’d like to add
this effect at the second text() command.

 

png('BaseMap.png',width=5.2,height=3.6,pointsize=5,units='in',bg=NA,restoreC
onsole=T,res=1200)

par(mar=c(5,0,0,0))

map('worldHires','brazil',ylim=c(-5.15,-4.55),xlim=c(-37,-36.1),type='n')

rect(-37.1,-5.25,-36,-4.9,density=NULL,angle=45,col='#dbf4ff',border=F)

plot(Batimetria,ylab='',xlab='',border=F,col=Cor$Cor,add=T)

plot(Municipios,ylab='',xlab='',col=rgb(245,232,140,max=255,alpha=255),add=T
,lwd=0.2)

axis(1,xaxp=c(-37,-36.1,5),cex.axis=1.5)

axis(2,yaxp=c(-5.15,-4.55,5),cex.axis=1.5)

text(Prof$Long,Prof$Lat,rownames(Prof),col='black',cex=0.9,srt=-24,font=2)

text(c(-36.96,-36.96,-36.865,-36.54,-36.37,-36.2),c(-4.96,-5.05,-5.11,-5.14,
-5.14,-5.14),c('Areia

Branca','Serra

Mangue','Macau','Guamaré','Galinhos'),col='Black',cex=1.3,font=2)

rect(-36.20,-4.56,-36.155,-4.565,density=NULL,angle=45,col='black',border='b
lack',lwd=0.1)

rect(-36.155,-4.56,-36.111,-4.565,density=NULL,angle=45,col='white',border='
black',lwd=0.1)

text(c(-36.20,-36.155,-36.111,-36.215),c(-4.573,-4.573,-4.573,-4.562),c('0',
'5','10','km'),col='white',cex=1)

Norte(-36.155,-4.60,0.02)

box(which='plot',lty='solid')

dev.off()

 

Thanks in advance!
