r - Transform multi dimensional array into factored data frame -


i have results tapply function creates array (with module names, animal names (rows) , test days (columns)) this

,, module1      [,d1] [,d2] [,d3] [,d4] [a1,]    1    3    2    1 [a2,]    2    1    3    2  ,, module3      [,d1] [,d2] [,d3] [,d4] [a1,]    1    3    2    1 [a2,]    2    1    3    2  ,, module3      [,d1] [,d2] [,d3] [,d4] [a1,]    1    3    2    1 [a2,]    2    1    3    2

what transform data frame module name , dimension names factors in data frame such this: 

module1  d1  a1  1 module1  d1  a2  2  module1   .. module3  d4  a1  1 module3  d4  a2  2 etc

which can use ggplot , other functions. there packaged/function let me this?

here's 1 way using plyr , reshape2:

adply(a, 3, function(x) melt(cbind(names=rownames(x), as.data.frame(x)))) #         x1 names variable value # 1  module1    a1       d1     1 # 2  module1    a2       d1     2 # 3  module1    a1       d2     3 # 4  module1    a2       d2     1 # 5  module1    a1       d3     2 # 6  module1    a2       d3     3 # 7  module1    a1       d4     1 # 8  module1    a2       d4     2 # 9  module2    a1       d1     1 # 10 module2    a2       d1     2 # 11 module2    a1       d2     3 # 12 module2    a2       d2     1 # 13 module2    a1       d3     2 # 14 module2    a2       d3     3 # 15 module2    a1       d4     1 # 16 module2    a2       d4     2 # 17 module3    a1       d1     1 # 18 module3    a2       d1     2 # 19 module3    a1       d2     3 # 20 module3    a2       d2     1 # 21 module3    a1       d3     2 # 22 module3    a2       d3     3 # 23 module3    a1       d4     1 # 24 module3    a2       d4     2

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
