Kenneth -
See ?if in the Details section. Specifically this part (at least in R
2.7),
"In particular, you should not have a newline between '}' and
'else' to avoid a syntax error in entering a 'if ... else'
construct at the keyboard or via 'source'."
The R interpreter can't 'see ahead' that you have an else statement.
Your program could validly end after your cons.expr, without the need
for an 'else'. This is why you should put your else on the same line,
possibly using {}s for clarity.
Best,

Why will this simple statement not work? I think I am following the
documentation for if(cond) statements, and I have tried wrapping the
cons.expr and alt.expr in {}, I get the same error. There is no example
in the help file, and this is not covered in the Introduction to R,
SimpleR or other tutorials I have looked into.
mxx=max(cpx_list$nMV);
mxy=max(trend_list$nMV);
if (mxx>mxy)
mxy=mxx
else
mxx=mxy
Error: unexpected 'else' in "else"
Why does this error message have the first 'else' in single quote and
second in double??
