Move legend text to the left legend box border

Hi,

in legend I'am coloring my text rather than using symbols or lines:

legend("bottomleft", txt, text.col=col, cex=0.7)

However, between the left legend box border and the text in txt is a
large empty space. Can I somehow move the text more to the left and get
also a smaller legend box?

Thanx in advance
