Multiple character replacement in R -


below part of code , can see, trying remove string of characters , meta characters. there way replacements in 1 line? tried writing symbols open , close parethesis after word function not work. 

{      p1 <- gsub("function", "", deparse(s)[1]);            #removing word "function"     p2 <- gsub("\\(", "", p1);                            #removing open parenthesis     p3 <- gsub("\\)", "", p2);                            #removing close parenthesis     p4 <- gsub("\\s", "", p3);                            #removing spaces     variables <- strsplit(p4,",");                        #separating variables  }

maybe not 1 line solution can simplify code this:

listtoreplace <- c("function", "\\(", "\\s")  string <- "function.... ...bbb((bbbb"  gsub(paste(listtoreplace,collapse="|"), "",     string)

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
