Finding aggregate correlation of multiple columns against one column in r -


i have data frame 11 columns out of 9 numeric. trying find out correlation of 8 columns against remaining column i.e., correlation of 8 variables 1 variable should generate 1 value of correlation instead of generating 9 different values in matrix.

is possible? or need calculate average correlation after calculating individual correlation?e.g., trying find correlation of x,y,z a. using mentioned methods matrix gives me indivual score of association x,y,z need 1 score takes account 3 x,y & z.

a simulated df presented below illustration purposes

          x            y           z   1   1.72480753  0.007053053  0.32435032  10 2   0.97227885 -0.844118498 -0.75534119  20 3  -0.53844294 -0.036178789  0.89396765  30 4   1.34695331  0.870119744  0.99400826  40 5   0.02336335  0.514481676  0.95894286  50 6  -0.15239307  0.386061290  0.73541287  60 7  -0.29878116  1.615012645 -0.04416341  70 8  -1.10907706 -1.581093487 -0.93293702  80 9   2.73021114 -0.130141775  1.85304372  90 10  0.22417487  1.170900385 -0.68312974 100

i can correlation of each row , variable want correlation of x,y,z combined a

corr.test(df[,1:3],df[,4])

i appreciate towards problem.

regards,

pearson correlation defined number relating 1 sequence (or vector) of values (look up). far know there no equivalent definition group of vectors another, take average vector (of 3 vectors) , correlate that.

to me @ least has more immediate geometric meaning taking average of 3 correlation values.

angularjs - ADAL JS Angular- WebAPI add a new role claim to the token -

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.
