Hello. I want to create some sequence of numbers . So far I used sequence which does not work always seq(CRagent[[1]]$xy[1],CRagent[[2]]$xy[1],by=0.01) Error in seq.default(CRagent[[1]]$xy[1], CRagent[[2]]$xy[1], by = 0.01) : wrong sign in 'by' argument Calls: seq -> seq.default if the parameters are in descending form. The ideal would be to be able to use seq like this seq(2,3,by=0.5) --&g...

Hello everyone. I am using ggplot and I need some help to merge these two plots into one. plot_CR<-function(x,y,agentid,CRagent){   library(ggplot2)     agent<-CRagent[[agentid]] # To make following expression shorter   ggplot((data.frame(x=CRX,y=CRY,sr=agent$sr)))+   geom_point(aes(x,y,colour=cut(sr,c(0,-10,-20,-30,-40,-50,-60,-70,-80))))+   geom_text(aes(x,y,color=cut(sr, c(0,-10,-20,-30,-40,-50,-60,-70,-80)), label=r...

Dear all, I would like to ask your help concerning an error message I get. I have the following struct str(CRagentInTime[[1]]) List of 2 $ timelag: int 0 $ CRagent:List of 50 ..$ :List of 3 .. ..$ CRmap: num [1:256, 1:256] NA NA NA NA NA NA NA NA NA NA ... .. ..$ xy : num [1:2] 10 177 .. ..$ sr : num [1:49] -94.9 -92.8 -79.5 -97.6 -78.4 ... and I wanted to select all the sr fields for every of ea...

Hello is there in R any operator that give you all the data of a matrix for example in matlab x(2,3) returns the 2ndth row and 3rdth column x(2,:) returns all the columns of the 2nd row. In R now I would like to print all the  CRagent[[i]][2]  CRagent[[:]][2] doesnot work of course. Other option is to make a loop with an index i that spans from 1:last element of CRagent[[]] but this is not that optimal. I would like to thank you in aavance for your help Best Regards Alex [[alternative HTML version deleted]]

Dear all, I have a data frame that is created like that data.frame(x=CRX[-1],y=CRY[-1],z=CRagent[[1]]$sr) the output looks like 45 116 162 -30.89105988567164 46 128  79 -42.66296679571184 47 180 195 -30.45626175641315 48 114  83 -45.26843476475688 49 118  73 -46.85389245327003 How can I select only the rows that their third column is higher that -45? This will return the following 116 162 -...

...tion that plots based on the input. This function is called plot_shad. When I call this function alone in the command line I get my plot. Then I tried to use another function as depicted_below to do some calculation before calling the function that does the plotting. plot_shad_map<-function(f,CRagent,agentid){   for (i in c(1:nrow(shad_map))){     for (j in c(1:ncol(shad_map))){      # Do something     }   }   plot_shad_f(shad_map) # This plots fine when used in command line. But inside this #function does not   return(shad_map) } Unfortunately I get no plot . What might be the problem? One m...

Dear all, seasons greetings, I had made a list of elements that I want to have  # list generator Agent<-list(id=NA, position=list(x=NA,y=NA)) # Make list of Agents AgentList<-rep(list(CRAgent),5) # Initialization. Is it shorter to do that with a lapply statement? for (i in c(1:length(CRAgentList))){   AgentList[[i]]$id=i } The created struct looks like > str(AgentList) List of 5  $ :List of 3   ..$ id                  : int 1   ..$ position            :List of 2   .. ..$ x: log...
