How to change the default font size in ggplot2

白昼怎懂夜的黑 提交于 2019-12-03 17:53:50
问题 I'd like to know if it is possible to change some default parameters of ggplot2 graphics, like font size for instance, for a whole R session. The idea is to avoid setting them for each plot. 回答1: Use theme_set() theme_set(theme_gray(base_size = 18)) qplot(1:10, 1:10) 回答2: Use theme_set if you want to update for the remainder of your active session: theme_set(theme_grey(base_size = 18)) If you only want to change one graph you can set the base_size in the theme: qplot(1:10, 1:10) + theme_grey

问题 I want to open a URL, such as http://www.example.com/ , at the end of a Perl script. I don't want to access it with WWW::Mechanize but actually show the web page to the user in a graphical web browser. There are ways to do this in Mac ( open URL ) and Windows, but I want a solution that works on any operating system, not just one. 回答1: The second hit on "open url" at search.cpan brings up Browser::Open: use Browser::Open qw( open_browser ); my $url = 'http://www.google.com/'; open_browser(

For HTTP responses with Content-Types suggesting character data, which charset should be assumed by the client if none is specified?

五迷三道 提交于 2019-12-03 16:42:51
问题 If no charset parameter is specified in the Content-Type header, RFC2616 section 3.7.1 seems to imply ISO8859-1 should be assumed for media types of subtype "text": When no explicit charset parameter is provided by the sender, media subtypes of the "text" type are defined to have a default charset value of "ISO-8859-1" when received via HTTP. Data in character sets other than "ISO-8859-1" or its subsets MUST be labeled with an appropriate charset value. However, I routinely see applications

Play 2.0 Scala: default selected/checked on form elements

自闭症网瘾萝莉.ら 提交于 2019-12-03 16:38:28
Can find nothing on the net re: this issue. I'm looking at the code on github for select , checkbox and friends but am completely missing the boat as to how one gets default selected/checked working. What is the deal here? The case class on which form in question is based has a default value for the problem field, but that does nothing. Do I need to apply a default value to the Form(mapping('foo-> boolean)) entry? If so, how? Ignorance is not bliss, drop some knowledge if you've got it... Thanks Not ideal, but see this thread for one way to achieve default values. @inputRadioGroup( field =

心不动则不痛 提交于 2019-12-03 16:21:46
I have a website which has been running on IIS7 for about 2 months. We have the default documents set up to load a default.asp page when users go to the domain with no page.

How to set a default layout in Magento 1.5 using local.xml?

試著忘記壹切 提交于 2019-12-03 15:51:17
So I've done some layouts that I want to use and I was thinking that setting this in your local.xml file would fix this for every page. Like this <default> <reference name="root"> <action method="setTemplate"> <template>page/mytheme.phtml</template> </action> </reference> </default> This however doesn't do anything. Instead if I go ...<customer_account_forgotpassword> <reference name="root"> <action method="setTemplate"><template>page/mytheme.phtml</template></action> </reference> </customer_account_forgotpassword> <customer_account_confirmation> <reference name="root"> <action method=

python decorator to display passed AND default kwargs

狂风中的少年 提交于 2019-12-03 15:35:40
I am new to python and decorators and am stumped in writing a decorator which reports not only passed args and kwargs but ALSO the unchanged default kwargs. This is what I have so far. def document_call(fn): def wrapper(*args, **kwargs): print 'function %s called with positional args %s and keyword args %s' % (fn.__name__, args, kwargs) return fn(*args, **kwargs) return wrapper @document_call def square(n, trial=True, output=False): # kwargs are a bit of nonsense to test function if not output: print 'no output' if trial: print n*n square(6) # with this call syntax, the default kwargs are not

Default values for System.Threading.ThreadPool.SetMaxThreads

别来无恙 提交于 2019-12-03 15:22:53
问题 Suppose, I don't set any values explicitly by calling the function: System.Threading.ThreadPool.SetMaxThreads What are the default values? 回答1: It depends on the .NET framework version, changed in 2.0, 3.0 and 4.0. In 2.0 it was 50 times the number of cores. In 3.0 (aka 2.0 SP1) it was 250 times the number of cores, 4.0 made it dynamic depending on bitness and OS resources. Max I/O completion threads was always 1000 if I remember correctly. In general, it is insanely high and a program should

Why does a Java constructor have to be public or protected for a class to be extended outside its package?

ⅰ亾dé卋堺 提交于 2019-12-03 14:47:46
The following is my ProtectedConstructor.java source code: package protectCon; public class ProtectedConstructor{ public int nothing; ProtectedConstructor(){ nothing = 0; } } And following is the UsingProtectedCon.java source: package other; import protectcon.ProtectedConstructor; public class UsingProtectedCon extends ProtectedConstructor{ //**Line 4** public static void main(String... a) { } } When I compile UsingProtectedCon.java , I get error at Line 4 shown above. It says that ProtectedConstructor() is not public ; so cannot be accessed outside package. However, since my class is public,
