order - getting largest values per row in R -

-

i trying rank values of row. trying see value largest, second largest etc etc.

here simple example:

test = c(0.005,0.007,0.009,-0.0008,0.5,-0.074) order(test) [1] 6 4 1 2 3 5 which.max(test) [1] 5

the function which.max correctly gives me column largest value, doesn't give me second largest, third largest etc., etc.

i believed use function order this, output of doesn't seem correct.

what doing wrong?

you have use decreasing parameter:

> order(test,decreasing=t) [1] 5 3 2 1 4 6

or alternatively reverse it:

> rev(order(test)) [1] 5 3 2 1 4 6

-
i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
