Try:

mxx = 2
mxy = 4
if (mxx > mxy) {
  print ("mxx reigns supreme")
} else {

  print ("mxy reigns supreme")
}

Subject: [R] If(cond) statement

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??
