With the example you offered (but failed to include as context):

You need to learn to use str()

str(bpl)
# output too long
 > str(bpl$panel.args.common] )
# output still too long

 > str(bpl$panel.args.common[c("x","y","z")] )
List of 3
  $ x: num [1:40000] -2.44 -2.44 -2.43 -2.42 -2.41 ...
  $ y: num [1:40000] -0.196 -0.196 -0.196 -0.196 -0.196 ...
  $ z: num [1:40000] 107 106 106 105 104 ...
