Value

Returns a data frame from a csv file into a dataframd called "results".

Returns a data frame from a csv file into a dataframd called "results".

Note

Exported earthquake data must have a .csv extension. The NOAA data is exported as a tab delimited file called "results" without a file extension designation. Specifically,

1. Data will be downloaded as a tab delimited file called "results" from the NOAA site. 2. The exported tab delimited file is added to the working directory. 3. The tab delimited file is given a .csv extension. 4. Use the R routine to import the tab delimited file to a dataframe.

Examples

# Downloaded NOAA file in tab delimited format with a .csv extension.
# Returns a dataframe with the default name "results."
## Not run: 

library(readr)
import_quake_data("results.csv")


## End(Not run)
