IF Statement to change codes


Tag : excel , By : Alex S

I hope this helps you . I am not sure what you are trying to achieve but this is one way of replacing text MU999 with R. Martinez within rows 2 and 3000 in column E
Sub Main()

    Dim c As Range
    For Each c In Range("E2:E3000")
        If StrComp(c, "MU999", vbTextCompare) = 0 Then
            c = "R. Martinez"
        End If
    Next

End Sub
Sub Main()

    Dim c As Range
    For Each c In Range("E2:E3000")
        If StrComp(c, "MU999", vbTextCompare) = 0 Then
            c = "R. Martinez"
        ElseIf StrComp(c, "MU111", vbTextCompare) = 0 Then
            c = "replaced with M. Martinez"
        ElseIf StrComp(c, "MU666", vbTextCompare) = 0 Then
            c = "666 is not evil!"
        End If
    Next

End Sub
Sub Main()

    Dim c As Range

    For Each c In Range("E2:E3000")

        Select Case UCase(c)
            Case "MU999"
                c = "R. Martinez"
            Case "MU111"
                c = "replaced with M. Martinez"
            Case "MU666"
                c = "666 is not evil!"
        End Select
    Next
End Sub

Can we add a statement in between MATLAB codes?

With these it helps Is it possible to add statements in between the codes. , You need to comment those statements like this
r(:,1) = a(:,1) ... % this is a constant 
         - a(:,2); % this is a variable 

what does the codes with the 'with' statement do?

it should still fix some issue When so many examples are non-self explanatory and the documentation not too helpful, Beginning Python I came across with statement used in a code as such: , I commented to try explain;
#this is your standard method definition
def r_f(fn, n, vl):
        #these are local variables
        cn, rd = 0, 0
        #we are saying;
        #in the scope of this with statement, the variable f
        #is equal to the file object returned by open
        with open(fn, 'r') as f:
            #for every line in the file
            #(because readlines returns a list of all the lines)
            for value in f.readlines():
                #increment this variable by 1
                rd += 1
                #if rd is greater than n
                if rd > n:
                    #break out of this loop
                    break
                #if the integer representation of the line we read
                #is equal to v1
                if int(value) == vl:
                    #then increase this variable by 1
                    cn += 1
        #we return this value to the function that called us
        return cn  

Excel if statement to R codes

wish help you to fix your issue I am new to R and trying to use R to run the report I am currently doing in excel. Most of the topics here have been so helpful to me translating excel formula to R codes, however, I am struggling to generate codes for below excel if statement , We can do a nested ifelse after reading the dataset
df1 <- read.csv("yourfile.csv", stringsAsFactors=FALSE)
ifelse(df1[,7]=="SEA" & df1[,6] %in% c("FCL", "BCN"),
        df1[,35]*40, ifelse(df1[,7]=="AIR", df1[,36]*66, NA))

Why is a Bash variable empty inside of an if statement empty, but not outside of the if statement?

Any of those help , Use here-doc as this:
cat > variables.sh <<-'EOF1'
#!/bin/bash
echo "Please enter your first name:"
read -e -i "Bob" FIRST_NAME
echo "Please enter your last name:"
read -e -i "Marley" LAST_NAME

echo "First name: $FIRST_NAME"
echo "Last name: $LAST_NAME"
if [[ "$FIRST_NAME" == "Bob" ]] ; then
echo "Last name: $LAST_NAME"
fi
EOF1
