r - Can I get coordinates of the circle created by `floating.pie` function in `plotrix`? -


i wondering how can x, , y values forming "circle" of pie chart produced "plotrix" package in r?

as example, how can x, , y values making "circle" of pie chart produced the r code below:

install.packages('plotrix') library("plotrix")  plot(1:5, type="n", xlab="x", ylab="y",xpd=t) floating.pie(3, 3, 1, col="white", radius=1)

you can obtain on own using polar coordinates. , floating.pie doing same.

let radius, edges, xpos , ypos same feed floating.pie, circle determined following points:

radius <- 1; edges <- 200; xpos <- ypos <- 3  x <- radius * cos(seq(0, 2 * pi, length = edges)) + xpos y <- radius * sin(seq(0, 2 * pi, length = edges)) + ypos circle <- cbind(x, y)  plot(1:5, asp = 1)  ## set axis ratio 1:1 polygon(circle)

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

python - ValueError: No axis named 1 for object type <class 'pandas.core.series.Series'> -

i´m new programming. i´m trying use scipy minimize, had several issues , gotten through of them. right code, i'm not understanding why i´m getting error. par_opt = so.minimize(fun=fun_obj, x0=par_ini, method='nelder-mead', args=[series_pt_cal, dt, series_caudal_cal]) not enough info given op, somewhere in code it's specified operate data frame column (axis=1) on object pandas series. if code typically works occasional gives errors, check degenerative cases data frame may have 1 row. pandas has nasty habit of guessing want -- may decide reduce 1-row data frame series (e.g., apply() function; can disable using reduce=false in there). add line of code check object isinstance(df, pd.dataframe) or else convert offending pandas series data frame, s.to_frame().t problems had deal with.

java - How to provide dependency injections in Eclipse RCP 3.x? -

everyone! i'm trying deal eclipse rcp 3.x application. i've read lot of articles dependency injection in rcp e4 applications. can use di in rcp 3.x apps? i found perfect link di in e4. idea how use in rcp 3.x app? first of all, i'm interested in own objects injection (btw, how add own object application context?). best regards in 3.x code can ieclipsecontext necessary use contextinjectionfactory using ieclipsecontext workbenchcontext = platformui.getworkbench().getservice(ieclipsecontext.class); to workbench context. in view or editor can current part context using: ieclipsecontext partcontext = getsite().getservice(ieclipsecontext.class);
