From memory, R is quite slow, and has syntax I found really ugly. Dots as part of names (my.variable), $ for member access, operators wrapped in % for pointwise operations, eg %*% for pointwise multiplication. These probably shouldn’t matter but did for me. FWIW the statistical offering was fantastic.
