files = list.files(pattern="*.csv") data_list = lapply(files, read.table, header = TRUE) This read every file and adds it to a list. Afterwards, if all data.frame have the same structure they can be combined into one big data.frame: df <- do.call(rbind, data_list)

LINQ extension methods on IEnumerable<T> take actual methods1, whether anonymous methods: //C# Func<int,bool> fn = x => x > 3; var list = new List<int>() {1,2,3,4,5,6}; var query = list.Where(fn); 'VB.NET Dim fn = Function(x As Integer) x > 3 Dim list = New List F...
