Today’s challenge is to
read in a dataset, and
describe the dataset using both words and any supporting information (e.g., tables, etc)
Read in one (or more) of the following data sets, using the correct R package and command.
Find the _data
folder, located inside the posts
folder. Then you can read in the data, using either one of the readr
standard tidy read commands, or a specialized package such as readxl
.
# A tibble: 2,930 × 3
state county total_employees
<chr> <chr> <dbl>
1 AE APO 2
2 AK ANCHORAGE 7
3 AK FAIRBANKS NORTH STAR 2
4 AK JUNEAU 3
5 AK MATANUSKA-SUSITNA 2
6 AK SITKA 1
7 AK SKAGWAY MUNICIPALITY 88
8 AL AUTAUGA 102
9 AL BALDWIN 143
10 AL BARBOUR 1
# … with 2,920 more rows
# ℹ Use `print(n = ...)` to see more rows
Add any comments or documentation as needed. More challenging data sets may require additional code chunks and documentation.
Using a combination of words and results of R commands, can you provide a high level description of the data? Describe as efficiently as possible where/how the data was (likely) gathered, indicate the cases and variables (both the interpretation and any details you deem useful to the reader to fully understand your chosen data).

## Challenge Overview
Today's challenge is to
1) read in a dataset, and
2) describe the dataset using both words and any supporting information (e.g., tables, etc)
## Read in the Data
Read in one (or more) of the following data sets, using the correct R package and command.
- railroad_2012_clean_county.csv ⭐
- birds.csv ⭐⭐
- FAOstat\*.csv ⭐⭐
- wild_bird_data.xlsx ⭐⭐⭐
- StateCounty2012.xlsx ⭐⭐⭐⭐
Find the `_data` folder, located inside the `posts` folder. Then you can read in the data, using either one of the `readr` standard tidy read commands, or a specialized package such as `readxl`.
```{r}
library(readxl)
railroad <- read_csv("_data/railroad_2012_clean_county.csv")
railroad
#import the railroad 2012 data into R
```
Add any comments or documentation as needed. More challenging data sets may require additional code chunks and documentation.
## Describe the data
Using a combination of words and results of R commands, can you provide a high level description of the data? Describe as efficiently as possible where/how the data was (likely) gathered, indicate the cases and variables (both the interpretation and any details you deem useful to the reader to fully understand your chosen data).
```{r}
#| label: summary
spec(railroad)
dim(railroad)
colnames(railroad)
filter(railroad)
```
