ODBC and R

I suggest replacing the R/SQL code with the following:

```
library("RSQLite")
dbfile = "C:/Users/pfsmy/OneDrive/UoM/Carpentry/Datasets/SN7577.sqlite"
mydb = dbConnect(drv = SQLite(), dbname=dbfile)
results = dbGetQuery(mydb, "SELECT * FROM SN7577")
dbDisconnect(mydb)
```

Using `dbGetQuery` is more straightforward and makes the code easier to read.
