Challenge 1

Code

library(tidyverse)

Error in library(tidyverse): there is no package called 'tidyverse'

Code

knitr::opts_chunk$set(echo = TRUE, warning=FALSE, message=FALSE)

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.xls ⭐⭐⭐⭐

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.

Code

library(readr)

Error in library(readr): there is no package called 'readr'

Code

railroad <- read_csv("_data/railroad_2012_clean_county.csv",show_col_types = FALSE)

Error in read_csv("_data/railroad_2012_clean_county.csv", show_col_types = FALSE): could not find function "read_csv"

Code

railroad

Error in eval(expr, envir, enclos): object 'railroad' not found

Code

print("Num rows :")

[1] "Num rows :"

Code

print(nrow(railroad))

Error in nrow(railroad): object 'railroad' not found

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).

The data consists of 3 cols viz. state, county and employee count. There are a total of 2930. The data most likely is gathered from a survery conducted across the country.

Code

print("dimensions of data : ")

[1] "dimensions of data : "

Code

dim(railroad)

Error in eval(expr, envir, enclos): object 'railroad' not found

Code

print("Column Names : ")

[1] "Column Names : "

Code

colnames(railroad)

Error in is.data.frame(x): object 'railroad' not found

Code

filter(railroad, state == "AL", county=="HOUSTON")

Error in match.arg(method): object 'county' not found
