i trying plot formula. x approaches 0 right, y should approaching infinity, , curve should going upwards close y-axis. instead gets cut off @ y=23 or so. my_formula = function(x){7.9*x^(-0.5)-1.3} curve(my_formula,col="red",from=0 ,to=13, xlim=c(0,13),ylim=c(0,50),axes=t, xlab=na, ylab=na) i tried play from= parameter , , got needed when put from=-4.8 have no idea why works. in fact x doesn't less 0, , from/to should represent range of x values, they? if explain me, amazing! thank you! by default, curve chooses 101 x-values within (from, to) range, set default value of n argument. in case means there aren't many values close enough 0 show full behaviour of function. increasing number of values plotted n=500 helps: curve(my_formula,col="red",from=0 ,to=13, xlim=c(0,13),ylim=c(0,50),axes=t, xlab=na, ylab=na, n=500)

(the following has been edited make understandable.) we want compare actual json object expected json object, complication json objects may contain other json objects. using net.sf.json api this. have tried following approaches: we have tried json objects' keys lists (to preserve keys' order) , indexes of keys in lists. we have tried adding (flattening) keys , values in json objects pair of map objects. in case, had problems duplicate keys in nested json objects. addressed making values in map lists of values json objects. after discussion team, need modify approach follows: (the following has not been edited ...) now wanna compare key , values in result json , expected json (must need check format) while traversing each key in result json parallelly want check same(key , value) in expected json. first of all, if preserving order of keys in json objects because order important meaning of json, abusing json. json specs make clear order of key in js...

i have data set , wherein want predict component , along components need predict proportions seems me classification+regression. there python library that? there deep learning method ? understand task can done in 2 separate step there way combine these operations. the solution format expect prediction must get class : 34% class b : 46% class u : 20% assuming classes exist z, , composition may have increase or decrease in number of classes. latent class regression the problem describing can solved latent class regression, or cluster-wise regression, or it's extension mixture of generalized linear models members of wider family of finite mixture models, or latent class models. it's not combination of classification (supervised learning) , regression per se, rather of clustering (unsupervised learning) , regression. basic approach can extended predict class membership using concomitant variables, makes closer looking for. in fact, using latent class models c...

i not able understand use case when can use ntlm domain, ntlm host, ssl,allow expired certs been used. any appreciated. ntlm microsoft's implementation of kerberos protocol. used when author , publishers have 1 or more of following conditions valid: not on same windows domain. don't share common ad provider. kerberos ports (for eg. 88) blocked. windows server being accessed via ip address rather it's host name. ntlm challenge-response protocol these ntlm host , domain names parameters used protocol identify client (which author server in case) along user name , password. in reality, never use in linux environment , use in modern windows network have better ad security options (like trusted domains , subnets). ssl options there workaround in situations publisher's https certificate has expired , want continue replication. assuming own publisher server in network, trust publisher server's identity , ignore expired certificated until renew...

we have access automation software opening instance of ms access 2016 using com , fetching data of tables/reports etc access database. once done, close ms access database - calling database.close() assigning null value referenced variables calling closecurrentdatabase() of access application object finally calling quit() method of access application object assigning null value access application referenced variables calling gc.collect() & gc.waitforpendingfinalizers() in separate thread. doing of above kills ms access 2013 instances fails ms access 2016. processes linger on time , keep consuming ~50 mb ram , ~10% cpu though our automation completed , our code has quit. find these processes killed time later. this lingering on of processes causing high cpu / ram usage issues find more 50 instances open. is there known issue in ms access 2016 while closing or connect post activity (like connect server , send data) when application.quit called. would appreciate a...

i need check if 2 things true decide class. have been trying find solution because believe should pretty common problem. maybe i'm searching wrong things. i want have 2 conditions in 1 statement, if called? i've tried similar things this: ng-class="{'in-behalf-of-background-color' : parameters.username == quote.inbehalfof } ,{'not-in-behalf-of-background-color' : ((parameters.username != quote.inbehalfof) && (quote.inbehalfof != 'null'))}" as can see want check parameters.username != quote.inbehalfof , if quote.inbehalfof != null in same condition. possible? try code; you want multiple condition define 1 object , define conditions key value pair {key1:value1, key2: value2} ng-class="{'in-behalf-of-background-color' : parameters.username == quote.inbehalfof, 'not-in-behalf-of-background-color' : ((parameters.username != quote.inbehalfof) && (quote.inbehalfof)) }"
