#Included in this R project folder is the same CSV file from the Module $0$ Download.

#$------$SETUP$------$

#Ensure the tidyverse is installed and loaded.

#Load the CSV file into a data frame.

#Remove any records with empty$/$NA values

#$------$ASSIGNMENT$------$

#$1.$ In one statement using the pipe operator, create a new data frame formed

# by first selecting the name and diameter columns$/$variables and then filters

# out trees with diameters in the range of $27$ inches to $30$ inches $($inclusively$).$

# In Canvas for question $1,$ copy and paste the statement you used here.

#$2.$ How many records are in this new data frame?

#$3.$ How many Black Walnuts $($JUGLANS NIGRA $-$ BLACK WALNUT$)$ are in the

# data frame created in question $1?$

#$4.$ With the data frame created in question $1,$ use the mutate function to add a

# third column$/$variable named "TREE$\_$DBH$\_$CM$"$ to this data frame, which contains

# the TREE$\_$DBH column converted from inches to centimeters.

# Conversion Formula: CM $=$ IN $*2\mathrm{.}54$

# In Canvas for question $3,$ copy and paste the statement you used here.

#The coordinates for the northwest corner of Logan Square are:

# Longitude $($X$)$: $-75\mathrm{.}172,$ Lat $($Y$)$: $39\mathrm{.}959$

#The coordinates for the southeast corner of Washington Square are:

# Longitude $($X$)$: $-75\mathrm{.}151$; Lat $($Y$)$: $39\mathrm{.}946$

#$($See the Boundary.png image in this project folder$)$

#$5.$ Using the original data frame from the "SETUP" section, how many trees are

# within this boundary? using R studio
