What does it mean by 1e 6?
As others have mentioned, practically speaking, 1e6 is scientific notation for 10^6 which is 1000000 or better known as 1 million. But as has already been mentioned, by David, this is actually treated as a double in C and the value is actually 1000000.0 .
What does 1e 06 mean in R?
So 1e6 is 110^6=1,000,000 and 2.1e-4 is 5.110^-4=0.00051. In Stata one can figure out what the exponential number means by typing: display 1e6, whereas in R it is enough to type: format(1e6, scientific=F). Now, if you want R to display only scientific number instead, you want to set options as: options(scipen = -10).
