[R] values of list of variable names

[Christian]

Hi,

I have searched the documentations of eval, substitute, expression, and 
I cannot make work something like the values of a list of variable names:

lis <- ls(pattern="pr") # all variables with names containing 'pr'

What is the mantra giving me the _values_ of the variables whose names 
are  contained in 'lis'. eval(parse(ls(pattern="pr"))) will not do but 
returning TRUE.

TIA
C.
