Use of for loop to delete rows of specific instances in R

wish helps you Could you please let me know know how I could only keep the row with the highest hands for every different players? I intended to do a for loop but I could not figure out how to solve it. , Try this:
code :
library(dplyr)

df %>%
  group_by(Player) %>%
  filter(Hands == max(Hands))
# A tibble: 3 x 3
# Groups:   Player [3]
  Player `PKMP ID` Hands
   <int>    <fctr> <int>
1   1141   PKMP002 23658
2   1714   PKMP016   678
3   1745   PKMP032  6821

Delete specific Rows without using Do Until loop

This might help you You can rewrite it to a For loop. This will allow you to cut out a bit of code. I would also recommend adding static variables outside of the loops. This will remove any unnecessary processing. I ran this and it seemed to run quite quickly.
code :
Sub main()

    Dim i As Integer
    Dim ch As String, str As String
    Dim ws1 As Worksheet
    Dim wb1 As Workbook
    Dim last As Long

    Set wb1 = ThisWorkbook
    Set ws1 = wb1.Sheets("Source")
    last = ws1.Cells(Rows.Count, "F").End(xlUp).Row

    str = 314

    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationManual

    For i = last To 2 Step -1
        If Left(ws1.Cells(i, 6), 3) = str Then
            ws1.Cells(i, 6).Rows.EntireRow.Delete
        End If
    Next

    Application.ScreenUpdating = True
    Application.Calculation = xlCalculationAutomatic

End Sub

Delete specific rows from selection in for each loop

should help you out Always run from the bottom to the top when deleting rows or you risk skipping rows (as you have noticed).
code :
'don't dim inside a loop
Dim r As Long
Dim strArray As Variant
Dim intCount As Integer
Dim intWords As Integer

With Selection
    For r = .Rows.Count To 1 Step -1

        strArray = Split(Selection.Cells(r).Value & " ", " ")
        intWords = 0

        For intCount = LBound(strArray) To UBound(strArray) - 1
            If dict.Exists(Trim(strArray(intCount))) Then
                dict(Trim(strArray(intCount))) = dict(Trim(strArray(intCount))) + 1
            Else
                dict.Add Key:=Trim(strArray(intCount)), Item:=1
                intWords = intWords + 1
            End If
        Next intCount

        If intWords = 0 Then
            .Cells(r).EntireRow.Delete
        End If

    Next r
End With

VBA Loop: if cell contains specific value then delete the row containing the value and the next 3 rows below

will be helpful for those in need Hi there I am trying to loop through a long report that removes deletions. , I think you just to fix this part and put the colon in the quotes.
code :
If Range("B" & x).Value = "DELETE" Then Range("A" & x & ":I" & x + 4)).ClearContents
If Cells(x,"B").Value = .....
Sub RemoveDel()
lastrow = Cells(Rows.Count, "B").End(xlUp).Row
For x = 1 To lastrow

    If Range("B" & x).Value = "DELETE" Then Range("A" & x & ":I" & x + 4).ClearContents

Next x
End Sub

Delete 2 Rows above if specific cell is blank [Loop]

This might help you One way to achieve this would be as follows, the reason I delete the rows below (586) before checking the rows above (505) is because once you delete the row, the rows shift up, in essence changing the row numbers:
code :
Sub foo()
Dim ws As Worksheet: Set ws = Sheets("Sheet1")
    If ws.Range("B586").Value = "" Then ws.Rows("584:585").Delete
    If ws.Range("B505").Value = "" Then ws.Rows("503:504").Delete
End Sub

For Each loop won't delete all rows with specific values

Hope that helps Modifying a collection you're iterating is always a bad idea. Sure you could start at the bottom and call it a day, but then your next question is going to be "my code is painfully slow, how do I make it faster?"
Have a CombineRanges function responsible for Union-ing ranges:
code :
Private Function CombineRanges(ByVal source As Range, ByVal toCombine As Range) As Range
    If source Is Nothing Then
        Set CombineRanges = toCombine
    Else
        Set CombineRanges = Union(source, toCombine)
    End If
End Function
Dim toDelete As Range
Dim cell As Range
For Each cell In ActiveSheet.Range("B11:B25")
    If cell.Value <> "Total" Then Set toDelete = CombineRanges(toDelete, cell)
Next

If Not toDelete Is Nothing Then toDelete.EntireRow.Delete
