Discarding Files of Different Lengths

Question

I have a set of imported CSV files stored under the variable name data. The imported files are of different lengths and I would like to be able to discard the ones below a certain length.

I believe that Mathematica has a Select[] function that might be right for this, but I haven't been able to manage it yet. My elementary attempt looks like this, but it returns a set of empty sets.

newdata = Table[Select[data[[i]], Length[data[[i]]] > 47], {i, 1, Length[data]}]

Any help would be appreciated, thanks!

Answer 1

The following can be used if the csv files are imported as strings.

Select automatically iterates over a List of data.

So given a data like this

data = RandomWord["CommonWords", 10]

The following will select the data of more than a certain length:

Select[data, StringLength[#] > 7 &]

---

If the data is already parsed like

data=Table[Table[RandomWord["CommonWords",5],RandomInteger[{10,20}]],{20}];
Dimensions /@ data

then you can use the following to select those with more than 15 rows of data

newdata=Select[data, Length[#]>15 &];
Dimensions /@ newdata
