Use superscripts in R axis labels

Question

Using base graphics in R  how can I add superscripts to axis labels  as one might want to when plotting latitude and longitude axes on a map   Consider this example   plot -100 -50  50 100  type  n   xlab     ylab     axes FALSE  axis 1  seq -100  -50  10   labels paste abs seq -100  -50  10     o    W   sep      axis 2  seq 50  100  10   labels paste seq 50 100 10    o    N   sep      box     Produces a nice frame around a map   It would be even nicer to make the degree symbol superscript     This can usually be done in other plotting functions such as mtext   and text   using expression paste       or substitute   but how to do it in this case

It works the same way for axes  parse text  70 o N   will raise the o as a superscript  the  N is to make sure the N doesn t get raised too    labelsX parse text paste abs seq -100  -50  10      o      W   sep      labelsY parse text paste seq 50 100 10     o      N   sep      plot -100 -50  50 100  type  n   xlab     ylab     axes FALSE  axis 1  seq -100  -50  10   labels labelsX  axis 2  seq 50  100  10   labels labelsY  box

The other option in this particular case would be to type the degree symbol      R seems to handle it fine  Type Option-k on a Mac to get it  Not sure about other platforms

The Thunder Chimp You can split text in such a way that some sections are affected by super or sub  script and others aren t through the use of    For your example  with splitting the word  moment  from  4th  -   plot rnorm 30   xlab   expression  4  th  moment
