Okay guys, I have, what I'm sure, is an entry-level problem. Still, I cannot explain it. Here's my code and its error:
> sample1 = readHTMLTable(http://www.pro-football-reference.com/boxscores/201609150buf.htm, which = 16)
Error: unexpected '/' in "sample1 = readHTMLTable(http:/"
It's having a problem with the second front-slash? Not only does every URL have two front-slashes, but I've poured through countless examples of this function, both on this site and others, and they've all formatted this code in this way. So, what am I doing wrong?
Additionally, I've tried it without the back-slashes:
> sample1 = readHTMLTable(www.pro-football-reference.com/boxscores/201609150buf.htm, which = 16)
Error: unexpected symbol in "sample1 = readHTMLTable(www.pro-football-reference.com/boxscores/201609150buf.htm"
Here, I'm not even sure which symbol it's talking about.
Please explain.
The issue is that you need to place your url in quotes (""). The following does return the table from your specified url:
sample1 = readHTMLTable("www.pro-football-reference.com/boxscores/201609150buf.htm")
As you probably know, the "which=" parameter is used to select which of the tables in that page you would like to retrieve. However my own attempts show that only 1 and 2 work. Could you tell me which table you are attempted to read into R? If this method doesn't end up working you can also attempt to read in the entirety of the webpage and parse out the table in question.
Hope this helps get things started!

I am new to sage and have got a code (link to code) which should run.
I am still getting an error message in the decoding part. The error trace looks like this:
in decode(y)
--> sigma[i+1+1] = sigma[i+1]*(z)\
-(delta[i+1]/delta[mu+1])*z^(i-mu)*sigma[mu+1]*(z);
in sage.structure.element.Element.__mul__
if BOTH_ARE_ELEMNT(cl):
--> return coercion_model.bin_op(left, right, mul)
in sage.structure.coerce.CoercionModel_cache_maps.bin_op
--> action = self.get_action(xp,yp,op,x,y)
...... some more traces (don't actually know if they are important)
TypeError: positive characteristics not allowed in symbolic computations
Does anybody know if there is something wrong in this code snipped? Due to previous errors, I changed the following to get to where I am at the moment:
.coeffs() changed to .coefficients(sparse=False) due to a warning message.
in the code line sigma[i+1+1] = sigma[i+1](z)\
-(delta[i+1]/delta[mu+1])*z^(i-mu)*sigma[mu+1](z); where the error occurs, i needed to insert * eg. sigma[i+1]*(z)
I would be grateful for any guess what could be wrong!
Your issue is that you are multiplying things not of characteristic zero (like elements related to Phi.<x> = GF(2^m)) with elements of symbolic computation like z which you have explicitly defined as a symbolic variable
Phi.<x> = GF(2^m)
PR = PolynomialRing(Phi,'z')
z = var('z')
Basically, the z you get from PR is not the same one as from var('z'). I recommend naming it something else. You should be able to access this with PR.gen() or maybe PR(z).
I'd be able to be more detailed, but I encourage you next time to paste a fully (non-)working example; trying to slog through a big worksheet is not the easiest thing to track all this down. Finally, good luck, hope Sage ends up being useful for you!
I am trying to build the inline segment to filter the pages (ex. to separate the pages for blogs and games) using the function BuildClassificationValueSegment() to get the data from Adobe Analytics API,
I have tried some thing like
report.data.visits <- QueueTrended(reportsuite.id,date.from,date.to,metrics,elements,
segment.inline = BuildClassificationValueSegment("evar2","blog","OR")).
Got error like :
Error in ApiRequest(body = report.description, func.name = "Report.Validate") :
ERROR: segment_invalid - Segment "evar2" not valid for this company
In addition: Warning message:
In if (segment.inline != "") { :
the condition has length > 1 and only the first element will be used
Please help on the same.Thanks in advance...
I recommend you to declare the InlineSegment in advance and store it in a variable. Then pass it to the QueueTrended function.
I've been using the following syntax to generate an inline segment:
InlineSegment <- list(container=list(type=unbox("hits"),
rules=data.frame(
name=c("Page Name(eVar48)"),
element=c("evar48"),
operator=c("equals"),
value=c(as.character("value1","value2"))
))
You can change the name and element arguments in order to personalize the query.
The next step is to pass the InlineSegment to the QueueRanked function:
Report <- as.data.frame(QueueRanked("reportsuite",
date.from = dateStart,
date.to = dateEnd,
metrics = c("pageviews"),
elements = c("element"),
segment.inline = InlineSegment,
max.attempts=500))
I borrowed that syntax from this thread some time ago: https://github.com/randyzwitch/RSiteCatalyst/issues/129
Please note that there might be easier ways to obtain this kind of report without using InlineSegmentation. Maybe you can use the selected argument from the QueueRanked function in order to narrow down the scope of the report.
Also, I'm purposefully avoiding the BuildClassificationValueSegment function as I found it a bit difficult to understand.
Hope this workaround helps...
I am running WYSIHTML5 to allow myself to enter email text and format it for sending as HTML. However when I view HTML of the formatted text I get classes associated with elements for Colors. This is expected behavior but since I need to send the output in an email hence I would like to have those colors to be in Inline CSS, since I cannot attach CSS files with the email like that. Example here
<span class="wysiwyg-color-green">Testing</span>
That is if I select green color for text: Testing. Is there any way to modify that green to become part of html itself like
<span style="color:green">Testing</span>
I have tried to search for this but could not find, so I am not asking without first looking for it. If anybody could please just point somewhere. Even a link to any guide to this, will do. I do not wish that you spend time writing code for me.
You could do it with php :
str_replace ( 'class="wysiwyg-color-green"', 'style="color:green"' ,$html)
You can do the same with javascript, altrough it's always safer to do everything server-side.
http://www.w3schools.com/jsref/jsref_replace.asp
Here's the javascript code I used but may be a good idea to heed Jean-Georges warning above:
replaceColorStylesWithInlineCss = function (htmlContents){
result = htmlContents.replace('class="wysiwyg-color-black"', 'class="wysiwyg-color-black" style="color:black"');
result = result.replace('class="wysiwyg-color-silver"', 'class="wysiwyg-color-silver" style="color:silver"');
result = result.replace('class="wysiwyg-color-gray"', 'class="wysiwyg-color-gray" style="color:gray"');
result = result.replace('class="wysiwyg-color-maroon"', 'class="wysiwyg-color-maroon" style="color:maroon"');
result = result.replace('class="wysiwyg-color-red"', 'class="wysiwyg-color-red" style="color:red"');
result = result.replace('class="wysiwyg-color-purple"', 'class="wysiwyg-color-purple" style="color:purple"');
result = result.replace('class="wysiwyg-color-green"', 'class="wysiwyg-color-green" style="color:green"');
result = result.replace('class="wysiwyg-color-olive"', 'class="wysiwyg-color-olive" style="color:olive"');
result = result.replace('class="wysiwyg-color-navy"', 'class="wysiwyg-color-navy" style="color:navy"');
result = result.replace('class="wysiwyg-color-blue"', 'class="wysiwyg-color-blue" style="color:blue"');
result = result.replace('class="wysiwyg-color-orange"', 'class="wysiwyg-color-orange" style="color:orange"');
return result
};
Note: I kept the wysiwyg styles in there because I'm saving to the db and want it to display properly in the wysihtml5 section when I load it again. DRY it up if you're clever.
I'm trying to read or redirect the test console output. I'm doing an AssertAreEqualIgnoringOrder and I need to parse some of the values within the failures. The failures output looks like this:
Expected elements to be equal but possibly in a different order.
Ensure the list of idols matches with the db
Equal Elements : ["98932", "670945", "6747749", "6770804", "7110604", "13280109", "13280121", "13280149", "14448042", "14448336", "15726213", "17009409", "17245584", "93123", "2212314", "10129661", "13280123", "13280125", "13280135", "13280144", "17245263", "18784003", "1112597", "2885514", "8505390", "13279857", "15032800", "17009391", "17009396", "17009398", "17880635", "18340462", "3606775", "13280116", "13280133", "13280137", "14448341", "15050039", "16711731", "17008920", "17009377", "17009381", "17009402", "17245606", "17901335", "865871", "6029748", "17009372", "17009386", "17009406", "17245604", "19113286", "19865372"]
Excess Elements : ["14419207"]
Missing Elements : ["17241620"]
How can I read this directly or redirect it to a file? If I can just parse the output, I can work it afterwards with some RegEx, that will not be a problem.
Another solution would be to parse the Gallio report file, but I'm sure there is a faster way.
Can you help me, please?
Thanks,
Andrei
I try to use the like-Button and therefor the open graph.
My problem is, that "&" and "$" chars are always replaced by & and %24
Of course, thats the normal case, but I need a clean $ and no entity there, becuase otherwise the link is not working for this image.
I could see, that facebook´s raw output produces \u0024 and so on (seems to be XKBSymbols). But if I try to put this symbols in the link in my typo3 meta-tag, it doesnt work either.
I already tried:
#page.headerData.12345.htmlSpecialChars = 0
#page.headerData.12345.htmlSpecialChars.preserveEntities = 1
#page.headerData.12345.rawUrlEncode = 0
to solve this problem, but none of those work.
Please give me a useful hint.
Thanks
try to write to your php code trough htmlspecialchar php function and add it to header with
$GLOBALS['TSFE']->additionalHeaderData['somekey'] = '...'
