Detailed Steps

First use the following code to download the daily weather data.

library(rnoaa)
library(xts)
library(dygraphs)

d=meteo_tidy_ghcnd("USW00014733",
                   date_min = "2016-01-01", 
                   var = c("TMAX"),
                   keep_flags=T)
d$date=as.Date(d$date)

Remaining steps:

1. Convert d into an xts time series object using xts(). You will need to specifify which column has the data (d$tmax) and order.by=d$date. See ?xts for help.
2. Use dygraph() to draw the plot
3. Set the title of the dygraph to be main="Daily Maximum Temperature in Buffalo, NY"
4. Add a dyRangeSelector() with a dateWindow of c("2017-01-01", "2017-12-31")

Output

Your final graph should look something like this:
