Dear all,
There appears to be a bug in how constrOptim handles ... arguments that
are suppose to be passed to optim, according to the documentation. This
means you can't get the hessian to be returned, for example (so this is
a real problem, and not just a question of mistaken documentation).
Hi, this is a minor problem in solve.default but I didn't see anyone
mention it. The function does not give "correct" error-handling if given
non-square matrix, LINPACK=F, and matrix has names attributes (either
row or column names).
Demo:

Hi,
This is not a bug, but an enhancement suggestion. "strwidth" only gives the
width of the text according to the x-axis user coordinates, and similarly
for "strheight". Even if the par setting "srt" is changed to rotate the
text, the resulting width (resp. height) is in terms of the non-rotat
Hi,
This is not a bug, but a simple enhancement suggestion: that axis( ) also
allow option "col" to take a vector of colors equal to the length of
"labels". Currently it allows it, in the sense that there is no error
message, but the function will use just the first element of the vector.
