我有一个数据集Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim cmd As New OleDb.OleDbCommand
' add data to table '
If Not cnn.State = ConnectionState.Open Then
' open connection '
cnn.Open()
End If
cmd.Connection = cnn
If Me.txtID.Tag & "" = "" Then
cmd.CommandText = "INSERT INTO [Training log] ([ID], [Runner Name], [Running Average Speed], [Cyclying Average Speed], [Swimming style] , [Calories Burned]) VALUES ('" & Me.txtID.Text & "' , '" & Me.txtRunnerName.Text & "' , '" & Me.txtRunSpeed.Text & "' , '" & Me.txtCycleSpeed.Text & "', '" & Me.txtSwimStyle.Text & "', '" & Me.txtCaloriesBurned.Text & "')"
cmd.ExecuteNonQuery()
Else
cmd.CommandText = "UPDATE [Training log] SET ID=" & Me.txtID.Text & ", [Runner Name]='" & Me.txtRunnerName.Text & "', [Running Average Speed]='" & txtRunSpeed.Text & "', [Cyclyin Average Speed]='" & txtCycleSpeed.Text & "', [Swimming style]='" & txtSwimStyle.Text & "', [Calories Burned]='" & txtCaloriesBurned.Text & "' WHERE ID='" & txtRunnerName.Tag & "' "
cmd.ExecuteNonQuery()
End If
，它有一些观察结果和3个变量intrK1，V1，V2。这是我的命令：
V3显示错误，我无法弄明白。
qplot(log10(intrK1$V1),intrK1$V3,geom="point",fill=-intrK1$V3,xlab="Addtag(@)",ylab="Count")+geom_point(aes(weights=-intrK1$V2), position="dodge")
另外：警告信息：
Error: missing value where TRUE/FALSE needed
