i've fit gaussian curve below data, , calculate area under curve between values of x (e.g., x=6 x=18). below code produces following error: "error in f(x, c(m, s, a, b)) : unused argument (c(m, s, a, b))". also, have few negative values , need subtract negative area positive because i'm interested in 'net' value. x <- c(12.88, 12.9, 8.35, 10.52, 10.45, 8.44, 9.01, 9.96, 9.82, 9.83, 10.65, 10.69, 15.3, 15.33, 12.41, 12.43, 8.36, 8.43, 9.29, 9.25, 14.78, 14.87, 16.17, 16.23, 3.59, 4.37, 3.88, 19.88, 20.71, 20.33, 21.25, 22.09) y<-c(10.8, 9.62, 11.76, 5.12, 9.63, 4.80, 11.09, 7.42, 7.79, 9.76, 9.71, 8.13, 14.4, 14.85, 12.84, 11.59, 7.0, 6.49, 5.94, 4.93, 6.43, 7.8, 3.81, 2.6, -0.93, 5.3, 1.08, 0.39, -0.59, 2.77, 3.5, -2.08) df<-data.frame(x, y) #define gaussian function (y=amplitude*exp(-0.5*((x-mean)/sd)^2) + baseline) f<-function(x, theta) { m<-theta[1]; s<-theta[2]; a<-theta[3]; b<-theta[4]; a*exp(-0.5*((x-m)/s)^2) + b } f...

i wrote custom comparator treeset. debug, decided hardwire "compare()" return 0. surprise, 1 item entered set. why be? i'm doing best understand relationship between "set.add()" , "compare()". always returning 0 means items equal other items. that not prevent adding single possible item.

how can use command line command (or script), on windows, restart apache tomcat on debug mode @ same way eclipse ide (clicking on button @ servers view)? the command (or script) should contain arguments , parameters eclipse when click @ restart button. the motivation create global shortcut (like f12, example) restart apache tomcat on debug mode.

i've been instructed create customization on how unit price (purchline.purchprice) calculated. right when i'm creating new purchase order , select item, pulls pricing released products particular item. for customization, i'm going using 3 variables determine pricing. 1: itemid 2: current session date 3: customized field in purchase header as such, i'll need access purchline itemid on current line, , access purchtable access field in header. right there big process how pricing gets pulled released products, how system checks discounts, etc. my question is, can suggest best class/location check , modify final purchprice field gets set , inserted purchline ? i need last part of process of how purchprice gets calculated. i've looked around in pricedisc & priceconvert classes, salespurchline map, modified method of itemid field of form. axpurchline doesn't seem triggering @ when put breakpoints in them , create new purchase order lines. a...

i create documentlisteners so: mydocumentlistener dl = new mydocumentlistener(); tab.getdocument().adddocumentlistener( dl ); mydocumentlistener class provides event handling. however, want remove documentlistener not know how reference mydocumentlistener object created. the short answer is: need store mydocumentlistener object created someplace can access it. don't know structure of code, cannot best location save it. if want remove document listener added, do: mydocumentlistener dl = new mydocumentlistener(); tab.getdocument().adddocumentlistener( dl ); tab.getdocument().removedocumentlistener( dl ); ...but that's not want (why remove document listener added?) so, consider editing question more details structure of software, perhaps answerers can propose locations store documentlistener created.

i need accurately trimming video using ffmpeg c api. i’m seeing when input video stream has time_base of 1/48000 correctly selects trimmed start , end times. when input video stream has time_base other 1/48000 trim incorrect. time bases of 1/30000 , 1/24000 trim half expected video stream length - 10s instead of 20s. 1/25 trims nothing @ - output file size few kb. the audio stream appears trimmed correctly. for example if try trim first 20s of video video stream time base 1/30000, output mp4’s length 20s. has first 10s of video , first 20s of audio. i think i'm incorrectly calculating end_time i'm not sure why it's correct 1/48000 time_base streams. record[i].start_time = av_rescale_q((int64_t)( start_time * av_time_base ), default_timebase, in_stream->time_base); record[i].end_time = av_rescale_q((int64_t)( end_time * av_time_base ), default_timebase, in_stream->time_base); here more complete sample of code: int num_of_streams = ifmt_ctx->nb_s...

i've got jtable inside jscrollpane inside jpanel. make rows of jtable fill entire height of jpanel. like, if have 10 rows, strech out in height direction , fill entire jpanel, , and if add 10 more rows, rows should resize fit 20 rows in jpanel. i've managed make jscrollpane fill entire height of panel, table cells stay @ fixed size. there way this? suppose might possible fire event upon resizing window , set row height using window height , number of rows, sounds lot of work if there easier way happy :) in fact, initial guess comments (or things jtable#setfillsviewportheight ) don't here: affect height of table itself, not height of table cells . additionally, handling of cell heights bit tricky, , there may many corner cases, considering own cell renderer, row margins or fact may manually modify heights of individual rows (which internally causes construction of dedicated model manages these row heights). for simplest case, componentlistener sets globa...
