Is there a way to draw under names in MKMapView?

由 坚强是说给别人听的谎言 提交于 2019-12-11 16:35:09
问题 I've looked at the many fine threads on how to draw routes on an MKMapView and didn't see anything on this. I want to be able to draw information (e.g. traffic flow imagery for routes, possibly annotations) over the map terrain but under road names and numbers etc. It seems likely that there's no way to do this since the map / road names aren't exposed as separate layers in the mapkit? It does sound like I could draw a route under road names but that's because I can use Apple's API for that

问题 I am looking for a smarter way to create this type of name vectors in r (rmarkdown). I have: # 'mat' is a matrix with 10 columns colnames(mat)<-c("Comp 1","Comp 2","Comp 3", "Comp 4", "Comp 5","Comp 6" ,"Comp 7","Comp 8", "Comp 9", "Comp 10") Ideally I would do something with a for loop; for i =1:10 colnames(mat)<- c("comp 'i'") but this doesn't work. How can i do this? Thanks' in advance! 回答1: To use loop: mat as your dataset name for (i in 1:length(colnames(mat))){ colnames(mat)[i] <-

rbind data.frames without names

问题 I am trying to figure out why the rbind function is not working as intended when joining data.frames without names. Here is my testing: test <- data.frame( id=rep(c("a","b"),each=3), time=rep(1:3,2), black=1:6, white=1:6, stringsAsFactors=FALSE ) # take some subsets with different names pt1 <- test[,c(1,2,3)] pt2 <- test[,c(1,2,4)] # method 1 - rename to same names - works names(pt2) <- names(pt1) rbind(pt1,pt2) # method 2 - works - even with duplicate names names(pt1) <- letters[c(1,1,1)]

setnames in pipeline R code

由 社会主义新天地 提交于 2019-12-08 20:01:01
问题 I was wondering if it was possible to set the names of elements of a list at the end of a pipeline code. data <- input_vars %>% purrr::map(get_data) names(data) <- input_vars Currently I pass a string of variables into a function which retrieves a list of dataframes. Unfortunately this list does not automatically have named elements, but I add them "manually" afterwards. In order to improve readability I would like to have something as follows data <- input_vars%>% purrr::map(get_comm_data) %

Parsing Human Names and matching them in Ruby

问题 I'm looking for a gem or project that would let me identify that two names are the same person. For example J.R. Smith == John R. Smith == John Smith == John Roy Smith == Johnny Smith I think you get the idea. I know nothing is going to be 100% accurate but I'd like to get something that at least handles the majority of cases. I know that last one is probably going to need a database of nicknames. 回答1: I think one option would be to use a ruby implementation of the Levenshtein distance The

R: How to keep names while unnesting doubled nested tibble?

由 回眸只為那壹抹淺笑 提交于 2019-12-07 15:46:32
问题 at the moment I'm trying to figure out how to keep the names of an inner and other list nested within a tibble while unnesting. The .id parameter of the unnest function is the closest I found, but it starts to number the values instead of using the given names. here is a MWE with my idea of the final tibble: library(dplyr) library(tidyr) df.1 <- tibble( x = list("Foo","Bar"), y = list( list(a = list(aa = 1, ab = 2), b = list(ba = 6, bb = 22)), list(c = list(ca = 561, cb = 35), d = list(da =

How can I subscript names in a table from kable()?

问题 Given a data.frame A, how can I use subscripted rows and columns names? Eventually I want produce a table through kable() in rmarkdown (output: word document).

问题 first time poster, long time reader so be gentle with me :) See the following code which works to generate me timestamps for the beginning and end of every month in a financial year. int year = 2010; // Financial year runs from Sept-Aug so earlyMonths are those where year = FY-1 and lateMonths are those where year = FY int[] earlyMonths = {8, 9, 10, 11}; // Sept to Dec int earlyYear = year -1; for (int i : earlyMonths) { month = i; Calendar cal = Calendar.getInstance(); cal.clear(); cal.set

Losing names of dimnames of a table after cbind or rbind

由 ぐ巨炮叔叔 提交于 2019-12-06 02:36:45
问题 After cbind or rbind -ing a table object (for example, adding a margin of sums or somesuch), names of dimnames get lost (see y ). I found this "workaround" but was wondering if there's an out of the bag solution to this that looks less hacky. Perhaps something that can be done on the fly? I would like to keep the object of class table . > (x <- table(1:3, sample(1:3), dnn = c("rows", "cols"))) cols rows 1 2 3 1 1 0 0 2 0 0 1 3 0 1 0 > (y <- cbind(x, "4" = 4:6)) # "rows" and "cols" get lost 1
