We stop when the starting cell is the same as the one that we want to reach. This may be a bit of a long shot, and I don't play with rJava near as much as I used to, but if you look at the output of Sys.getenv(), is JAVAHOME set in your R session I know that in some cases, manually setting JAVAHOME in.

32bit or 64bit depending on your R version) Besides this you have to set your JAVAHOME variable, you can do it in your Rprofile.site file adding a line similar to this but with your own installation path. If the adjacent cell is neither visited, nor occupied, we do a recursive call to dfs(cell, end). Do you have an installation of Java in your system with matching architecture (i.e.For each of the adjacent cell, we check if the cell has not been visited yet and is not occupied.Sys.setenvJAVAHOME'C:/Program Files/Java/jdk-11.0. Then start R and load anew the RJDBC library. Do you have an installation of Java in your system with matching architecture (i.e. We find all the adjacent cells of the starting cell (to find out where can we jump to). onLoad failed in loadNamespace() for rJava, details: call: dyn.load(file, DLLpath DLLpath.We add the starting cell to the list of visited cells.I will use the list of adjacent cells in the Depth First Search implementation.įinally, the Depth-First Search implementation will work like this: , rJava 0.9-3 OS X 10.7.4 Oracle Java 1.7R version 2.15.2 () - Trick or Treat Platformx8664-apple-darwin9.8.0/x8664 (64-bit. Then, I will need a method that returns all the adjacent cells for a given cell. It will hold the current state of the board ( 'B' stands for blue and 'O' stands for orange). In order to keep it simple, I'll use a two-dimensional array of the custom class Cell that I added as a static one. If I were you, I would implement the algorithm myself.įirst, you need to determine the structure/class which will represent your board with balls that occupy some of the cells. I wouldn't go for third-party library, because the algorithm implementation there would strongly depend on the way the graph is represented (there are plenty of options, like two-dimensional array, list of lists or some other custom class).
