format

问题 I am using the dprint package with knitr , mainly so that I can highlight rows from a table, which I have got working, but the output image leaves a fairly large space for a footnote, and it is taking up unnecessary space. Is there away to get rid of it? Also since I am fairly new to dprint, if anybody has better ideas/suggestions as to how to highlight tables and make them look pretty without any footnotes... or ways to tidy up my code that would be great! An example of the Rmd file code is

Some are 0.1 others are 1.759374, etc. And I want to format them so they are ALL in the form of "+0.0000000E+00" I tried doing number = '%1.7f' % oldnumber but that didn't work.

问题 I am creating a user signup form, and I am adding date of birth to the required fields. I have scoured google, github and stackoverflow for a good date of birth (date) regex, and found this: user.rb DateRegex = /^\d{4}-\d{2}-\d{2}/ validates_format_of :date_of_birth, :with => DateRegex new.html.erb <%=label_tag :date_of_birth %> <%=f.text_field :date_of_birth %> (I know that this will allow some bogus birth dates, but I prefer not to install anything like validate timeliness at this point.)

问题 ADTF dat file contains streams of data. In the .dat file there is only a stream name. To find the structure of the stream one has to go through DDL .description file. Sometimes the .description files are incomplete or are missing link from stream name to corresponding structure. Is there some additional information about structure name hidden in the .dat file itself? (Or my understanding is completely wrong?) 回答1: You must differ between ADTF 2.x and ADTF 3.x and their (adtf)dat file

问题 Is it possible to manipulate the spacing and size of dashed and dotted grid lines in ggplot using the themes?

Additionally, does anyone know if the x-axis and y-axis grid lines can be manipulated separately?
