QUESTION
I have a data frame where some of the hours in Time GMT
are missing.
Normally, the hours should be shown in a sequence from 00:00 to 23:00, but sometimes an hour is missed.
Where an hour is missing in the sequence, I would like to insert a new row.
The new row will be a copy of the previous row, but with the following columns changed as follows:
Time GMT
: will contain the next hour of the previous row. i.e, if previous == 5:00, new == 6:00Sample Measurement
: will contain the average between the previous value and the next value in Sample Measurement column.MDL
: will contain the average between the previous value and the next value in column MDL

I am trying to display multiple columns with multiple input options in Shiny. In the following codes, I can select one option for ctree
depth and plot the tree as well as the data table. Now, I want to compare that with another depth input. How can I duplicate the results for another depth (such as depth = 2) and plot it next to the existing plot?

ANSWER
Answered 2021-May-26 at 10:19You can use the width
and column
to achieve that. I used the dataset iris
for my example as yours was not reproducible. Inside the function, width
will control the row width, and column
will control column width. Both widths go from 1 to 12. Divide 12 by the number of columns you wish in that row :
QUESTION
I'm attempting to use Stormcrawler to crawl a set of pages on our website, and while it is able to retrieve and index some of the page's text, it's not capturing a large amount of other text on the page.
I've installed Zookeeper, Apache Storm, and Stormcrawler using the Ansible playbooks provided here (thank you a million for those!) on a server running Ubuntu 18.04, along with Elasticsearch and Kibana. For the most part, I'm using the configuration defaults, but have made the following changes:
- For the Elastic index mappings, I've enabled
_source: true
, and turned on indexing and storing for all properties (content, host, title, url) - In the
crawler-conf.yaml
configuration, I've commented out alltextextractor.include.pattern
andtextextractor.exclude.tags
settings, to enforce capturing the whole page
After re-creating fresh ES indices, running mvn clean package
, and then starting the crawler topology, stormcrawler begins doing its thing and content starts appearing in Elasticsearch. However, for many pages, the content that's retrieved and indexed is only a subset of all the text on the page, and usually excludes the main page text we are interested in.
For example, the text in the following XML path is not returned/indexed:
(text)
While the text in this path is returned:
Are there any additional configuration changes that need to be made beyond commenting out all specific tag include and exclude patterns? From my understanding of the documentation, the default settings for those options are to enforce the whole page to be indexed.
I would greatly appreciate any help. Thank you for the excellent software.
Below are my configuration files:
