axis(1, at = 1:5, labels = c(expression(E[g]), "E", expression(E[j]),

abline(h=.7, xpd=TRUE, lty=3)
yes. In this situation, padj = 1 is the fast solution. However, If there
are also superscript, then it's hard to alignment all the labels.
If R provide a mechanism that aligns the label in axis() or text() with
the baseline of the character without the super- and/or sub-script, that
will be terrific.
it seems that the above wish is on the Graphics TODO lists:
https://www.stat.auckland.ac.nz/~paul/R/graphicstodos.html
Allow text adjustment for mathematical annotations which is relative to
a text baseline (in addition to the current situation where adjustment
is relative to the bounding box).

Subject: [R] depth of labels of axis
Hi there,
With the following code,
plot(1:5, xaxt = "n")
axis(1, at = 1:5, labels = c(expression(E[g]), "E", expression(E[j]),
"E", expression(E[t])))
you may notice that the "E" within labels of axis(1) are not at the same
depth. So the vision of axis(1) labels is something like wave.
Is there a possible way to typeset the labels so that they are have the
same depth?
Any suggestions will be really appreciated. Thanks in advance.
Best regards,
Jinsong
