如何在R中创建以字符开头然后以数字开头的序列

Question

How to create a sequence starting with a character and then with numbers in R

I wanna to create a sequence like the following: y1998 y1999 y2000 till y2011

Answer 1

There's : :

1998:2011

And ' or " to create string constants:

'y'

And paste0 to concatenate both:

paste0('y', 1998:2011)

Note how the paste0 function is applied to the second parameter, element by element. That's one of R's strengths.
