r - Creating a sentence based on the values in a data frame -


i want create sentence based on values in data frame. have following data.frame:

canada <- c(50, 50, 50) korea <- c(70, 70, 70) brazil <- c(100, 100, 100) fruit <- rbind(canada, korea, brazil) colnames(fruit) <- c("apple", "orange", "banana")  fruit >        apple orange banana > canada    50     50     50 > korea     70     70     70 > brazil   100    100    100

when type canada, want output this:

canada canada consumes average number of apples, average number of oranges,  , average number of bananas.

so, tried following:

average <- 'average number of ' if(fruit$'apple' > 90) {   cat("canada",            average, fruit$'apple',            average, fruit$'orange',           "and ", average, fruit$'banana'       ) }

of course, doesn't work, , stuck here. can guide me right path? put in work learn!

here's attempt, assuming may have columns other apple / orange / banana, you'd want values in given row.

myfun <- function(val){   val <- tolower(val) # assuming row names in lower case   myrow <- fruit[val,]    phrase <- sapply(seq_along(myrow),                     function(x, n, i) {paste0("consumes average ", x[i], " of ", n[i], "s")}, # "s" added assuming there's plural number of fruits                    x=myrow, n=names(myrow))   phrase[length(phrase)] <- paste0("and ", phrase[length(phrase)], ".")   phrase <- paste(phrase, collapse = ", ")    cat(tools::totitlecase(val), phrase) }  > myfun("korea") korea consumes average 70 of apples, consumes average 70 of oranges, , consumes average 70 of bananas. > myfun("canada") canada consumes average 50 of apples, consumes average 50 of oranges, , consumes average 50 of bananas. > myfun("brazil") brazil consumes average 100 of apples, consumes average 100 of oranges, , consumes average 100 of bananas.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
