Andrew,x[] <- lapply(x, function(xx) { xx[is.nan(xx)] <- NA_real_ xx }) is different from x <- lapply(x, function(xx) { xx[is.nan(xx)] <- NA_real_ xx })indeed, the two are different -- but some ignorance of mine is exposed. i wonder, can you explain why the two are different?
x <- lapply(...) says "set x to the list on the RHS", so x becomes a list, not a dataframe.
x[] <- lapply(...) says "set the values in x to the values in the list on the RHS", so x retains its class.
