first of all, apologise. i know there numerous threads error, have tried numerous solutions , have not managed solve issue. i have tried transforming data numerous forms still same error, or ggplot2 not support data format. here code: library(ggmap) library(ggplot2) library(data.table) setwd("~/projects/reformat") map <- get_map(location = c(-4,54.5), zoom = 6) data <- read.csv('lonlatprice.csv') colnames(data) <- c('longitude','latitude','price') ggmap(map, extent = "device") + geom_point(aes(x = data$longitude, y = data$latitude), colour = "red", alpha = 0.1, size = 2) this data format like: > head(data) longitude latitude price 1 53.778274 -2.48129 147500 2 52.833819 -0.936527 182000 3 50.792457 0.046043 193000 4 51.476984 -0.612126 580000 5 51.460139 -0.01867 905000 6 52.235942 1.519404 641500 thanks in advance help, have ask...

i'm making game in want able drag camera across scene. wrote following code: // when dragging if(touchdetection.touchdragging && introbusy == false) { if(dragactive == false) { dragstartpos = touchdetection.touchpositionwp; camerastartpos = camera.main.transform.position; dragactive = true; camerafollowingplayer = false; } vector2 temp = touchdetection.touchpositionwp - dragstartpos; camera.main.transform.position = camerastartpos - new vector3(temp.x, temp.y, 0); } if(touchdetection.touchdragging == false) { dragactive = false; } during drag, however, camera move, has jitter while moving. further away drag, bigger jitter becomes. i've spent hours searching problem, have still not found solution. a couple of points 1. it's practice move cameras in lateupdate rather in update. allows camera render after bodies have been moved. ...

i have written downloader should used download text files, images. download files binaries. many of downloads work well, parts of text files , many image files corrupted. errors occur @ same files , @ same places (as long can tell when analysing text files). used code downloading: public file downloadfile(httpurlconnection connection) { return writefiledatatofile(getfiledata(connection)); } //downloads data of file , returns content string private list<byte> getfiledata(httpurlconnection connection) { list<byte> filedata = new arraylist<>(); try (inputstream input = connection.getinputstream()) { byte[] filechunk = new byte[8*1024]; int bytesread; { bytesread = input.read(filechunk); if (bytesread != -1) { filedata.addall(bytes.aslist(filechunk)); filechunk = new byte[8*1024]; } } ...

so i've been working on client involving simple form generates url , resultant page outputs table. form explicitly set method="post" , action="" , js handling url so: onsubmit="this.action='{site_url}/entries/'+this.survey.value+'/'+this.job_number.value;" the form works fine, after several dozen submissions (mostly re-submissions of same form), server has blocked ip (via csf). what has caused , how can prevent happening again? the owner of service using either cooperating or not. if he/she cooperating you, should ask them cause of issue. sure give information need know server, not encounter issue again long follow policies. if not cooperating you, well, unlucky event, without solution.
