r - Change name of point labels in -


i know how add point labels when using ggplot2 using geom_text()

p <- ggplot(mtcars, aes(x=wt, y=mpg, label=rownames(mtcars))) p + geom_text()

enter image description here

but if want change "fiat x1-9" "worst car ever" without changing entries in original dataframe? there way rename point in plot within geom_text()?

thanks much.

you can override aesthetic or use in initial expression:

nms <- rownames(mtcars) p + geom_text(aes(label = replace(nms, nms == "fiat x1-9", "worst car ever")))

edit

if not want create new object can use this. point of advice, don't become attached one-liners. fun, creating object best readability, debugging, , accuracy.

p + geom_text(aes(label = replace(rownames(mtcars), rownames(mtcars) == "fiat x1-9", "worst car ever")))

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
