@dewayne_green 

To install the sqldf package in R, you can use the following command:

1

install.packages("sqldf")

You can also install the latest version of the package directly from GitHub using the devtools package by running the following command:

1

devtools::install_github("ggrothendieck/sqldf")

After installation, you can load the package by running:

1

library(sqldf)

You should now be able to use the sqldf package and its functions in your R scripts.

Note that the sqldf package has a dependency on the RSQLite package, so if it is not already installed on your system, you may encounter an error message during installation. In that case, you can install it by running:

1

install.packages("RSQLite")

Once RSQLite is installed, you can proceed with installing sqldf using the first method mentioned above.
