limits

问题 I would like to limit the number of decimals when a data frame is imported. My .txt input have 16 decimals to each row in collumn "Value". My dataframe look like that: Value 0.202021561664556 0.202021561664556 0.202021561664556 0.202021561664556 ... My expected dataframe Value 0.20202156 0.20202156 0.20202156 0.20202156 ... Real input (DF) that not works: DF <- "NE001358.Log.R.Ratio -0.0970369274475688 0.131893549586039 0.0629266495860389 0.299559132381831 -0.0128804337656807 0

问题 This question already has answers here : Stack capacity in C# (5 answers) Closed 4 years ago . i wonder how much calls we can perform in stack in c# before we get stack overflow exception so i decided to write the following code static void Method2(int Calls) { if(!Calls.Equals(0)) Method1(--Calls);//if more calls remain call method1 and reduce counter } static void Method1(int Calls) { if (!Calls.Equals(0))//if more calls remain call method2 and reduce counter Method2(--Calls); } static void

问题 I want to generate multiple maps over a base map (TMap). Basically, the same map, but categorized by week. Okay, here's the base code: library(ggplot2) library(ggmap) library(lubridate) map=TMap + geom_point(aes(x=Lon, y=Lat, size=count, color=as.Date(y$`2016-35`$DateTime)), data=y$`2016-35`, alpha=1) + scale_colour_gradient(limits=as.Date(c(min(y$`2016-35`$DateTime), max(y$`2016-35`$DateTime))),low="navy", high="orange", name="Date", trans="date") ggsave(map,path=dir,filename = paste("l",

问题 I created a faceted set of three univariate densities -- comparing MCMC methods. Shown below For the moment, I don't care about the tails. So how can I change the x-axis limits on the plots above to be: c(-3,1) c(-2,0) c(-10, -8) Is this even possible? I've already read this thread from 2009, but it doesn't seem to work. Was this implemented? 回答1: You can always allow limits to be set independently for each facet by specifying + facet_wrap(...,scales = "free_x") There are also "free" and

问题 I am trying to compile a C program in Ubuntu 10.04 made for 8.04. It fails because we have used PATH_MAX and other constants that should be defined in limits.h . According to various resources, it should be part of a POSIX compatible C library. Is this a bug in Ubuntu 10.04 or is there a proper way of solving this? 回答1: POSIX defines many such limits to be optional. If a limit FOO is not defined in limits.h , it means the system may have no such limit or the limit might vary at runtime or

问题 I'm currently attempting to develop a sandbox using Docker. Docker spawns process through a running daemon, and I am having a great deal of trouble enabling the limits set forth in the limits.conf file such that they apply to the daemon. Specifically, I am running a forkbomb such that the daemon is the process that spawns all the new processes. The nproc limitation I placed on the user making this call doesn't seemed to get applied and I for the life of me can not figure out how to make it

问题 The method I've devised so far is this: func randRange (lower : Int , upper : Int) -> Int { let difference = upper - lower return Int(Float(rand())/Float(RAND_MAX) * Float(difference + 1)) + lower } This generates random integers between lower and upper inclusive. 回答1: Here's a somewhat lighter version of it: func randRange (lower: Int , upper: Int) -> Int { return lower + Int(arc4random_uniform(UInt32(upper - lower + 1))) } This can be simplified even further if you decide this function

问题 trying to add 45 different points to a map, but I just get OVER_QUERY_LIMIT returned, and no map. I am getting locations via a string search, then assigning the returned LatLng object to a new google Marker object String Search var geocoder = new google.maps.Geocoder(); geocoder.geocode( { 'address': x}, function(results, status) { if (status === google.maps.GeocoderStatus.OK) { var result = results[0].geometry.location; return result; } else { alert("Geocode was not successful for the

问题 I am trying to send a base64 image via Worklight adapter. I want to know which parameters size can the adapter handle? Can I use a 8MB Image and convert it to base64 (let's say it will become 12 Mega Byte on 1 parameter), and then send it successfully to worklight adapter? or there is a length limit for the adapter parameters? 回答1: Basically, there shouldn't be any limitation. But... I think you need to re-think why you would want to send a 12mb-sized image to your app (to the device,
