r - Tcl/Tk Referencing user-selected values in script -

-

a quick question regarding tcl/tk , r. below have slice of code corresponds tk button executes todo<-function(){...}.

my presumption both summary.mydata() , ggplot() commands execute. said, question whether or not have correctly coded each command reference correct selected variable (the tk widget controlling working fine, not depicted).

namely if arguments each command valid. 

summary.mydata<-summaryse(mydata, measurevar=paste(tx.choice1), groupvars=paste(tx.choice2),conf.interval=0.95,na.rm=true,.drop=false)

would read r as

summary.mydata<-summaryse(mydata, measurevar=measure, groupvars=group,conf.interval=0.95,na.rm=true,.drop=false)

and

ggplot(data=summary.mydata,aes(x=paste(tx.choice2),y=paste(tx.choice1)))+                       geom_errorbar(aes(ymin=formula(paste(tx.choice1),"-ci"),ymax=formula(paste(tx.choice1),"+ci")), colour="black", width=.5, position=pd)+                       geom_point(position=pd, size=3)+                       labs(title=paste("interval plot of",tx.choice1,"by",tx.choice2))

will read as

ggplot(data=summary.mydata, aes(x=group, y=measure))+     geom_errorbar(aes(ymin=measure-ci, ymax=measure+ci), colour="black", width=.5, position=pd)+     geom_point(position=pd, size=3)+     labs(title = "new plot title",x="x",y="y")

the slice reference:

todo<-function(){     tx.choice1<<-vars.name.num[as.integer(tkcurselection(tl1))+1]     tx.choice2<<-vars.name.fac[as.integer(tkcurselection(tl2))+1]     numb.select.num<<-length(tx.choice1)     numb.select.fac<<-length(tx.choice2)      windows()     if (numb.select.num!=0){       if (numb.select.fac==0){         stop(tkmessagebox(message="please select @ least 1 categorical variable!", icon="error"))       }        else if (numb.select.fac==1) {         if(tclvalue(intervalplot_title)=="" & tclvalue(intervalplot_x)=="" & tclvalue(intervalplot_y)==""){           summary.mydata<-summaryse(mydata, measurevar=paste(tx.choice1), groupvars=paste(tx.choice2),conf.interval=0.95,na.rm=true,.drop=false)           ggplot(data=summary.mydata,aes(x=paste(tx.choice2),y=paste(tx.choice1)))+                       geom_errorbar(aes(ymin=formula(paste(tx.choice1),"-ci"),ymax=formula(paste(tx.choice1),"+ci")), colour="black", width=.5, position=pd)+                       geom_point(position=pd, size=3)+                       labs(title=paste("interval plot of",tx.choice1,"by",tx.choice2))         } else {           summary.mydata<-summaryse(mydata, measurevar=paste(tx.choice1), groupvars=c(paste(tx.choice2)),conf.interval=0.95,na.rm=true,.drop=false)           ggplot(data=summary.mydata,aes(x=paste(tx.choice2),y=paste(tx.choice1)))+                       geom_errorbar(aes(ymin=paste(tx.choice1)-ci,ymax=paste(tx.choice1)+ci), colour="black", width=.5, position=pd)+                       geom_point(position=pd, size=3)+                       labs(title=tclvalue(intervalplot_title),x=tclvalue(intervalplot_x),y=tclvalue(intervalplot_y))         }         tkinsert(txt,"end",paste("\nintervalplot of", tx.choice1,"by",tx.choice2[1],"\n\n"))       } }

figured out, correct usage paste(tx.choice1,"-ci"). there no need add formula() condition.

i'm using unity3d networked multiplayer online game have large complex 3d terrain scene forest, trees, cliff, hills, mountains, bounders, etc. players can build structures sort of minecraft, , put them anywhere in scene, or move them around anytime. aside human controlled players, there automated ai players , objects animals roaming around scene following path. the problem how make these automated ai players , animals, able navigate around static , dynamic player created structures, because path follow can blocked player created structures, or other players , other ai objects, cliffs etc. have find away around them or on track if tumble down off high cliff example. so made navmesh , used navagents, takes care of static, non moving objects, how make ai players navigate around each other , dynamic structures created players can number in hundreds? i thought of adding navmeshobstacle everything, result in being attached hundreds of objects since user created structures b...
