I have a column with string values and a column with numeric values. I want to add to the numeric value of each row if the string column has a certain word in it

For example:

```
stringColumn  numericColumn 
----------------------------
yes            5
no             7
no             3
yes            4

```

The `numericColumn` already has random numbers in it, but after running the code it should add 1 point to the `numericColumn` if the `stringColumn = 'yes'`.

So the dataset would end up looking like this

```
stringColumn  numericColumn 
----------------------------
yes            6
no             7
no             3
yes            5

```
