Hi everybody!

I have a (stupid) question but I cannot find a way to do it!

I have a list like:
 > SPECSHOR_tx_Asfc
$cotau
    SPECSHOR Asfc.median
38    cotau    381.0247
39    cotau    154.6280
40    cotau    303.3219
41    cotau    351.2933
42    cotau    156.5327
$eqgre
     SPECSHOR Asfc.median
145    eqgre    219.5389
146    eqgre    162.5926
147    eqgre    146.3726
148    eqgre    127.6413
149    eqgre    274.2888
$gicam
     SPECSHOR Asfc.median
263    gicam    174.7445
264    gicam     83.4821
265    gicam    157.6005
266    gicam    153.7519
267    gicam    344.9775

I would just like to remove the column "SPECSHOR" (or extract the other 
one) so that it looks like
$cotau
     Asfc.median
38        381.0247
39       154.6280
40        303.3219
41        351.2933
42        156.5327
etc.

How should I do it? I know how to select each element like 
SPECSHOR_tx_Asfc[[1]], but I don't know how to select a single column 
within an element.

Could you please help me on that?

Thanks
Ivan
