Thanks for your clarification. In fact,
$ pdffonts figure.pdf
name type emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
LBSBWQ+Palatino-Italic Type 1C yes yes no 11 0
SLZFVF+Palatino-Roman Type 1C yes yes no 9 0
$
but if I specify
pdf(file="figure.pdf", family="URWPalladio")
I get
$ pdffonts figure.pdf
name type emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
RNPZMM+URWPalladioL-Ital Type 1C yes yes no 9 0
$
