i display values of ordered factor on barplot ggplot2 (ideally, otherwise standard plot). i have ordered factor one: "how satisfied exercises :" - absolutely not satisfied => value 1 - not satisfied => value 2 - satisfied => value 3 - satisfied => value 4 i want plot barplot mean , values "absolutely not satisfied" -> "very satisfied" on axis instead 1 -> 4. is possible ggplot2 ? in point of view, main difficulty plot mean of factor , not distribution of values (actually plot made transformation of ordered factor integer). here result of dput on dataset. structure(c(3l, 2l, 3l, 2l, 2l, 3l, 2l, na, 2l, 3l, 4l, 2l, 1l ), .label = c("pas du tout satisfait", "plutôt pas satisfait", "plutôt satisfait", "très satisfait"), class = c("ordered", "factor")) and here example of barplot (without values on axis...): the code following. toto <- structu...

this question has answer here: “is” operator behaves unexpectedly integers 10 answers i have doubt regarding id() in python. >>> x=2 >>> y=2 >>> id(x) 94407182328128 >>> id(y) 94407182328128 but if same list,i different id's >>> a=[1,2,3] >>> b=[1,2,3] >>> id(a) 139700617222048 >>> id(b) 139700617135528 why so? why int type id's same , why different lists? thanks in advance. python doesn’t have variables c. in c variable not name, set of bits; variable exists somewhere in memory. in python variables tags attached objects. example: tags exaple image regarding list part: you created new reference . more details illustrated in brilliant video: https://www.youtube.com/watch?v=enlaee1c7x4

how chain method references instances java 8? example: collections.sort(civs,comparator.comparing(civilization::getstrategy.getstrateglevel)); getstrategy of civilization instance returns strategy object instance has instance method getstrategylevel . why doesn't comparator.comparing method return comparator it's functional interface implemented lambda expression? in case, should use lambda, can't apply method reference directly: collections.sort(civs, collectors.comparing(c -> c.getstrategy().getstrateglevel())); though, there way use method reference here. assuming have class like class civilizationutils { public static integer getkeyextractor(civilization c) { return c.getstrategy().getstrateglevel(); } } the issue solved like collections.sort(civs, collectors.comparing(civilizationutils::getkeyextractor));

i have existing model predicts house prices, uses simple linear regression. input have date , output price. i wanted improve overall results have added 1 more feature. new feature distance estimated property. problem multiple/multivariate regressions performs bit worse simple regression. (all data normalised) do have ideas why happening , how can approach this? there dozens of possible reasons, list few: if new feature barely correlated trying predict - efficiently injecting noise system cannot expect better performance if have few data points more features can lead harder problem since using linear model, if new feature predictor, relation not linear dependent variable - model fail well linear regression such naive model, ridge/lasso regression might change result (especially lasso since deals better bad features)
