R help - May 2010 - How to rbind listed data frames?

I made a list (dataList) of data frames. The list looks like this (the  
first two elements):

[[1]]
     est         cond                           targets
1   400 exo_depth_65                        Hautklinik
2   300 exo_depth_65                       Ostturm_UKM
3   200 exo_depth_65 Kreuzung_Roxeler/Albert_Schweizer
...


[[2]]
     est    cond                           targets
1   400 control                        Hautklinik
2   220 control                       Ostturm_UKM
3   300 control Kreuzung_Roxeler/Albert_Schweizer
...

Now I would like to merge the data frames with rbind. It works fine  
this way:

rbind(dataList[[1]], dataList[[2]], ...)

but I would like to use lapply or a for loop to get rid of specifying  
the subscripts. The output of lapply(dataList, rbind) is always

      [,1]   [,2]
[1,] List,3 List,3

Thanks for help...

assuming all data frames have the same format
do.call("rbind", dataList)

will concatenate all data frames contained in your list object.
