The data file, cor-disc.csv begins with:
site_nbr,year,mon,day,hr,min,tz,disc
14171600,2009,10,23,00,00,PDT,8750
The first 7 columns are character strings; the 8th column is an integer.
After loading library(tidyverse) I ran read_csv() with this result:
cor_disc <- read_csv("../data/cor-disc.csv")
Rows:
415263 Columns: 8
── Column specification
────────────────────────────────────────────────────────────────────────────
Delimiter: ","
chr (5): mon, day, hr, min, tz
dbl (2): site_nbr, year
ℹ Use `spec()` to retrieve the full column specification for this data.
ℹ Specify the column types or set `show_col_types = FALSE` to quiet this
message.
1. What happed to the values in column 'disc?'
2. Why are site_nbr and year seen as doubles when they're character strings?
I've not found answers in the book or in ?read_csv.
What am I missing?
