r - Replacing elements of a vector -


i have following string:

string <- c("100 100 test 100 string")

i replace 100's in above string elements of vector:

replacement <- c(1000,2000,3000)

the first 100 of string should replace 1000, second 100 2000 , on. resulting string should follows:

result <- c("1000 2000 test 3000 string")

is there efficient way in r?

thank you.

not elegant, should do..

string <- c("100 100 test 100 string") temp <- unlist(strsplit(string, split = "\\s+")) replacement <- c(1000, 2000, 3000) temp[temp == "100"] <- replacement result <- paste(temp, collapse = " ")  result ## [1] "1000 2000 test 3000 string"

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
