path

问题 I know that I can find file name from full file path in R, but is there a way to define the path to the file just from the file name? Think about such scenario: you store the data file in the cloud (e.g. Dropbox) so the path for this file is slightly different at your home: read.table("path/user1/data.dat") and work: read.table("path/user2/data.dat") . Therefore, every time you want to read.table() you have to change one element of the path to match either you work or home path (on Mac OS X

问题 We are using Neo4J 2.0 embedded; we have a Graph with around 1 Million of Nodes, and 50 Million of relationships; we have to find N shortestPath but with a well known cost property We saw that there is no such method in GraphAlgo class of neo4j and we were thinking to use Chyper, but when run this query START startNode = node(269604), endNode = node(269605) MATCH path=(startNode)-[:CAR_MAIN_NODES_RELATION*]->(endNode) RETURN path AS shortestPath, reduce(cost=0, rel in relationships(path) |

问题 Being completely new in python I'm trying to run a command over a set of files in python. The command requires both source and destination file (I'm actually using imagemagick convert as in the example below). I can supply both source and destination directories, however I can't figure out how to easily retain the directory structure from the source to the destination directory. E.g. say the srcdir contains the following: srcdir/ file1 file3 dir1/ file1 file2 Then I want the program to create

问题 The problem You have an absolute path, but you want it to be relative to another path. Example: P:/SO/data/database.txt --> Now we want the filename to be relative to: P:/SO/team/lists/ ../../data/database.txt I have already found the Stack Overflow question How to convert absolute path to relative path in PowerShell? .
