tmap

问题 I have a simple question: How does one remove an automatically added legend in tmap in R? In this case, I want to remove that legend on the right, depicting 'level'. Here's what I've tried: tm_shape(densities$polygons)+ tm_polygons(col='level', palette='Reds', alpha=0.5, border.col = 'transparent') + tm_legend(show=FALSE) I have also tried: tm_shape(densities$polygons)+ tm_polygons(col='level', palette='Reds', alpha=0.5, border.col = 'transparent') + tm_layout(legend.show=FALSE) Not sure why

问题 Facing problem and out of ideas on figuring on how to implement parent-child relationship in Talend. Problem Statement: Having a feed file which has data in below format MemberCode|LastName|FirstName A|SHINE|MICHAEL B|SHINE|MICHELLE C|SHINE|ERIN A|RODRIGUEZ|DAMIAN A|PAVELSKY|STEPHEN B|PAVELSKY|TERESA (there are many more columns and many more rows - just few rows for reference purpose). LastName and FirstName are self-explanatory. MemberCode denotes the relationship. A will be parent, B or C

问题 I have made a map unsing tmap to include in a shiny app using leaflet . I have roughly what I want: a thematic map with fill color based on a SpatialPolygonsDataFrame, and when you click the map, a popup with extra information on the polygon. I would like to change the popup for a better layout when clicking. By default, the name in the dataset is displayed, but it is not really user friendly. Here is a reproducible example. library(tmap) library(leaflet) data(Europe) tmap_mode("view") carte

问题 I'm creating a thematic map of percent change per year for bird species. here is the code I have: tm_shape(grid83)+ tm_fill("trend", title = "Percent change per Year", textNA = "None counted", style="fixed", breaks=c(-Inf, -1.5, -0.25, 0.25, 1.5, Inf), palette = c("red", "orange", "yellow", "turquoise", "blue", "white"))+ tm_borders(NA)+ tm_shape(uscan83)+ # add US and CAN tm_borders()+ tm_layout( "Western Grebe", legend.title.size=1, legend.text.size = 0.6, legend.position = c("left","bottom

问题 I would like to plot a figure with small multiple maps using ggplot2::geom_sf . The challenge here is how to do this keeping all maps centered in the image and at the same spatial scale. Here is the problem (data for reproducible example below): A simple map using facet_wrap put all polygons at the same spatial scale, but they are not centered. ggplot(states6) + geom_sf() + facet_wrap(~name_state) Here is a solution from this SO question that uses cowplot . In this case, polygons are centered

问题 Short version: when executing the following command qtm(countries, "freq") I get the following error message: Error in $<-.data.frame ( *tmp* , "SHAPE_AREAS", value = c(652270.070308042, : replacement has 177 rows, data has 210 Disclaimer: I have already checked other answers like this one or this one as well as this explanation that states that usually this error comes from misspelling objects, but could not find an answer to my problem. Reproducible code: library(rgdal) library(dplyr)

问题 Example: I want to plot two tmap plots side by side, which are generated by this code. library(tmap) library(gridExtra) data(World) plot1= tm_shape(World, projection = "merc") + tm_layout("", inner.margins=c(-1.72, -2.05, -0.75, -1.56)) + tm_borders(alpha = 0.3, lwd=2) plot2= tm_shape(World, projection = "merc") + tm_layout("", inner.margins=c(-1.72, -2.05, -0.75, -1.56)) + tm_borders(alpha = 0.3, lwd=2) plot1 and plot2 work fine as single stand-alone plots: Problem: I have problems to put
