Dear Users,
I have the following text plotted inside a graphic:
text(16200, 2.8*0.97, expression(NH[3]==0.33-1.1 %*% 10^-5 %*% day),
adj=c(1,1))
I need to include square brackets in the expression around the ammonia to have
it plotted like that: [NO3-]. I tried instinctively to use %[% to plot the
brackets, but it did not work. Does anybody of you know what is the correct
syntax to plot square brackets inside an expression?
Thank you in advance,
José
