Hi Adam,I was not sure if my solution was correct.This is what I got using
ArcGIS to convert the same coordinates:
+proj=lcc +lat_1=49 +lat_2=77 +lat_0=49 +lon_0=-95 +x_0=0 +y_0=0 +datum=NAD83
+units=m +no_defs +ellps=GRS80 +towgs84=0,0,0"

c("Long",?"Lat"), class = "data.frame", row.names
= c(NA, -120L))

Is there any difference between these points and those converted in R?
