Here's a fairly minimal-case example in which the saved EPS does not match
the screen. The error comes when using bquote(.(i)) instead of bquote(1), as
demonstrated by the two minimally different cases below. Very strange. Any
clues as to why?
#---------------- begin -------------------
# Version A. X axis labels have subscripts as constants. EPS is correct.
windows()
layout( matrix( 1:2 , nrow=2 ) )
plot( 0 , 0 , xlab=bquote(mu[1]) )
plot( 0 , 0 , xlab=bquote(mu[2]) )
savePlot( file="SavePlotTestA.eps" , type="eps" ) # Axis labels are correct
in EPS.
# Version B. X axis labels have subscripts as variable index. EPS is wrong!
windows()
layout( matrix( 1:2 , nrow=2 ) )
for ( i in 1:2 ) {
plot( 0 , 0 , xlab=bquote(mu[.(i)]) )
}
savePlot( file="SavePlotTestB.eps" , type="eps" ) # X-AXIS OF PLOT 1 IS
WRONG IN EPS.
#-------------- end ---------------------
Thanks!
