r - dividing a long column to many short ones by a condition -


i have long column of numbers. want r make new column every time value changes zero. example column: 

90.1194354  87.94788274  80.34744843  64.06080347  30.40173724  0  0  0  0  0  16.28664495  23.88707926  29.31596091  48.85993485  13.02931596  0  0  0  7.600434311  20.62975027  29.31596091  32.5732899

for example want 3 columns.

thanks!

i don't know how expect have columns of different lengths. pad them na?

this solution uses rle , splits vector list:

temp <- c(90.1194354, 87.94788274, 80.34744843, 64.06080347, 30.40173724,            0, 0, 0, 0, 0, 16.28664495, 23.88707926, 29.31596091, 48.85993485,            13.02931596, 0, 0, 0, 7.600434311, 20.62975027, 29.31596091,            32.5732899)  x <- rle(temp == 0) split(temp, rep(seq_along(x$lengths), times = x$lengths))[c(true, false)] # $`1` # [1] 90.11944 87.94788 80.34745 64.06080 30.40174 #  # $`3` # [1] 16.28664 23.88708 29.31596 48.85993 13.02932 #  # $`5` # [1]  7.600434 20.629750 29.315961 32.573290

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
