My actual plot call is long and complicated, so I tried to simplify it in
the last message.....here is the actual, using David's proposed solution.
It is not working. What I want to see printed is the following (with
degree symbols after 73 and 296). Since I reuse this string in various
ways, I would like to build a variable to hold it that I can plug into
plots when needed:
*Hours from Reference Time: 201302060000 Model span = 24.00 hrs o ?73
b ?296*
So I set xlab=printXlab value with David's solution, below, in the plot
(this is the actual printXlab value, instead of the simplified one):
* xl = bquote( .(Orthophase[i,j] )*degree )**printXlab<-paste("Hours
from
Reference Time:",RefTimeString,"Model span
=",format(magDt,digits=3,nsmall=2),"hrs
o",Orthophase[i,j],xl,"
b",Bathyphase[i,j]) *
and here is the result I get (weird duplicates....but most importantly, no
degree symbol:
Hours from Reference Time: 201302060000 Model span = 24.00 hrs o ?73 *
Hours from Reference Time: 201302060000 Model span = 24.00 hrs o ?73 ?73
Hours from Reference Time: 201302060000 Model span = 24.00 hrs o ?73 degree
b ?296 b ?296
b ?296
----------------------
So, I tried to set xlab as Uwe's proposal (without paste, and without
commas):
printXlab<-expression("Hours from Reference Time:" RefTimeString
"Model
span =" format(magDt,digits=3,nsmall=2) "hrs o" *
Orthophase[i,j] *
degree" b"* Bathyphase[i,j] * degree) # degree~C
I get "unexpected symbol at ^RefTimeStrng" so it doesn't like the
missing
commas.
Then I try it with commas, except around the degree parts:
printXlab<-expression("Hours from Reference Time:" RefTimeString
"Model
span =" format(magDt,digits=3,nsmall=2) "hrs o" *
Orthophase[i,j] *
degree" b"* Bathyphase[i,j] * degree) # degree~C
It runs, but here is what prints:
Hours from Reference Time:
?Then I try with all commas replaced by *:
printXlab<-expression("Hours from Reference Time:"* RefTimeString
*"Model
span =" * format(magDt,digits=3,nsmall=2) * "hrs o" *
Orthophase[i,j] *
degree * " b"* Bathyphase[i,j] * degree * " ") #
degree~C
?And I get degree signs (sort of)!! But the rest is wrong. The variables
are not evaluated:
Hours from Reference Time:RefTimeStringModel span =format(magDt, 3, 2)hrs
oOrthophasei? bBathyphasei?
?I don't really understand what state is required for the degrees to
print....?
