default

to simplify my daily R interactions, I'd like to set up default colors for all my plots. For example, let's say I want to have all plots made with red lines (like in gnuplot...:-) ) So far, here is a snippet of my .Rprofile setHook(packageEvent("grDevices", "onLoad"), function(...) grDevices::X11.options(width = 14, height = 8, type = "Xlib", xpos = 600, ypos = 30, canvas = "grey87")) suppressPackageStartupMessages( require(Defaults) ) suppressPackageStartupMessages( require(utils) ) suppressPackageStartupMessages( require(graphics) ) setDefaults("plot.default",frame.plot=FALSE, type='l', col

I was trying to learn how to use the "new" C11 Generic expressions but I ran into a wall. Consider the following code: #include <stdlib.h> #include <stdio.h> #define test(X, Y, c) \ _Generic((X), \ double: _Generic((Y), \ double * : test_double, \ default: test_double \ ), \ int: _Generic((Y), \ int * : test_int, \ default: test_int \ ) \ ) (X, Y, c) int test_double(double a, double *b, int c); int test_int(int a, int *b, int c); int test_double(double a, double *b, int c) { return 1; } int test_int(int a, int *b, int c) { return 2; } int main() { double *t = malloc(sizeof(double)); int *s =

I tried all possible things to let vim set filetype to 'txt' to all new files I create (in a new tab) but it doesn't work. This is p.e. what I've read on the web a few times: au BufRead,BufNewFile *.txt setlocal ft=txt (to put in _vimrc) However it doesn't work. Can anyone help me? Curt Nelson The following line, added to your .vimrc , will set the filetype to text if it is not already set. autocmd BufEnter * if &filetype == "" | setlocal ft=text | endif All files are considered plain text unless you have file-type detection turned on or explicitly set the file-type. However, Vim lets you set

I've just checked and it's allowed to create a table with a column that is NULL by default, although it's a UNIQUE KEY at the same time: CREATE TABLE IF NOT EXISTS `u789` ( `column1` varchar(10) DEFAULT NULL, UNIQUE KEY (column1) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; As I understand, it looks odd and has not much sense. I expected the second insert of INSERT INTO u789 VALUE (NULL); will fail. But, it inserts first, second, third NULL value without any problems. Who can explain me why it iserts second and third columns if NULL is already in the table? This is a theoretical question (as I

The screenshot show 3 typical definitions of data type: id (autoincrement), a title and a number. 1.- Which are differences between: none and NULL ? 2.- Do I must choose as defined: '' for varchar types when I want an empty string? 3.- Do I must put an as defined: 0 default value for autoincrement int types? Default none means there is no default value. If a value is not provided on an insert, the query will fail with a "no default value error". NULL is the actual NULL value meaning if no value is provided on an insert the column will default to NULL (empty). For varchar you can set default to

In our SVN repo, we store tags like this: trunk project_a project_b branches project_a branch_x branch_y project_b tags project_a 1.0 1.1 project_b 1.0 When I run the Maven release plugin's " prepare " goal on project A, by default it creates the tag as "tags/project_a-x.x", which does not match my tag naming scheme above. I am thus depending upon whoever does the release (i.e. a fallible human) to spot this and change the tag to "tags/project_a/x.x". How can I tell the release plugin to use the correct format by default? The "prepare" goal has a " tag " configuration option that claims to do

I was trying to download/update python nltk packages on a computing server and it returned this [Errno 122] Disk quota exceeded: error. Specifically: [nltk_data] Downloading package stop words to /home/sh2264/nltk_data...

I have a binded TextBlock , XAML: <TextBlock Text="{Binding MyText}"/> I know the FallbackValue can be used if the Binding isn't available, but this happens at run time ? Is there any way to show a default value at design time ? It would make things easier if I could see a value when designing my windows instead of an empty TextBlock . Thanks Scroog1 If you would prefer a less verbose version of Ian Bamforth's answer , you can just do <TextBlock Text="{Binding MyText, FallbackValue=None}"/> IBam Adapting an example from this question. This works for me - the text "None" is shown in the

I would change default sms app on Android 4.4.2 I use this code: Intent sendIntent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT); sendIntent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, context.getPackageName()); startActivity(sendIntent); How can i solve this? And how can i ask to change default sms app with my app? My Receiver: <receiver android:name="receiver.SMSHandlerReceiver" android:permission="android.permission.BROADCAST_SMS" > <intent-filter> <action android:name="android.provider.Telephony.SMS_DELIVER" /> </intent-filter> </receiver> Thank you.
