format - How to display a nested collection with .ps1xml file in powershell -

-

i have hierarchical object structure this:

public class department {     public string name { get; set; }     public string manager { get; set; }     public employee[] employees { get; set; } }  public class employee {     public string name { get; set;}     public string speciallity { get; set; } }

how can create custom .ps1xml file let me display department(s) follows:

    department : testers     manager    : p.h. boss  name                       speciallity ----------                 ----------------------------- employee              .net employee           biztalk yet                powershell ...                        ...       department : developers     manager    : wally  name                       speciallity ----------                 ----------------------------- employee              .net employee           biztalk yet                powershell ...                        ...

the main problem i'm having how can define <view> item selected department, based on tablecontrol, displays department.employees in table control.

i can display employee(s) fine using view:

<view>     <name>employee</name>     <viewselectedby>         <typename>employee</typename>     </viewselectedby>    <tablecontrol>         <tableheaders>             <tablecolumnheader>                 <label>name</label>                 <width>30</width>             </tablecolumnheader>             <tablecolumnheader>                 <label>speciallity</label>                 <width>50</width>             </tablecolumnheader>         </tableheaders>         <tablerowentries>             <tablerowentry>                 <wrap/>                 <tablecolumnitems>                     <tablecolumnitem>                         <propertyname>name</propertyname>                     </tablecolumnitem>                     <tablecolumnitem>                         <propertyname>speciallity</propertyname>                     </tablecolumnitem>                 </tablecolumnitems>             </tablerowentry>         </tablerowentries>     </tablecontrol> </view>

and can format departments using list format:

<view>     <name>testresultset</name>     <viewselectedby>         <typename>department</typename>     </viewselectedby>     <listcontrol>         <listentries>             <listentry>                 <listitems>                     <listitem>                         <label>department</label>                         <propertyname>name</propertyname>                     </listitem>                     <listitem>                         <propertyname>manager</propertyname>                     </listitem>                 </listitems>             </listentry>         </listentries>     </listcontrol> </view>

but how add table of employees after department?

i think need make use of <groupby>...</groupby , <control><customcontrol>...</customcontrol></control>

take @ this ps1xml format file discutils module, haven't had chance play myself yet may put on right path.

see help about_format.ps1xml has info, though little light on examples aspects.

when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

time series - R growth rate calculation week over week on daily timeseries data -

i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
