### mean over all cells
sapply(myData, function(x) mean(x))
### mean over all columns
sapply(myData, function(x) colMeans(x))

Subject: Re: [R] About cal
I'm trying to get a new dataframe or whatever to call, which has the same
structure with each file as listed above. For each cell in the new
dataframe or the new file, it is the average value from former dataframes
at the same location. Thanks.

Are you trying to take the mean over all cells, or over rows/columns within
each dataframe. Also, are these different dataframes stored within a list or
are they standalone?
