In this chapter, we focus on what map layers are available in tmap and how they differ. Chapter 6, on the other hand, is all about how to present information given in variables using colors, sizes, and shapes. The main function to visualize polygons is tm_polygons().

The values of a given variable can be expressed by different categorical or sequential colors in polygons. Lines can be also colored by one variable, but also widths of the lines can represent values of another quantitative variable.

tm_lines.Rd Map layer that draws lines. Supported visual variables are: col (the color), lwd (line width), lty (line type), and col_alpha (color alpha transparency).

Jan 8, 2023 · Implementation using tm_add_legend might look something like this, although it's hard to display the dotted red line segment with lwd = 3 in the legend from my point of view. tm_borders(alpha = 0.4, lwd = 0.1, col = "blue") +. tm_fill(col = "BIR79", style = "equal") +. tm_shape(sample_data) + . tm_borders(col = "red", lwd = 3, lty = 4) +.

Feb 28, 2025 · Map layer that draws lines. Supported visual variables are: col (the color), lwd (line width), lty (line type), and col_alpha (color alpha transparency). col = tm_const(), col.scale = tm_scale(), col.legend = tm_legend(), col.chart = tm_chart_none(), col.free = NA, lwd = tm_const(), lwd.scale = tm_scale(), lwd.legend = tm_legend(),

Jan 24, 2018 · Would anyone be able to show me how to produce a single interactive plot that contains: points which are labelled and which have the lines connecting them? You need to join the two tm_shape calls by a + operator to a single tmap object.

Luckily, throughout the entire registration process, you have different options for protecting your brand in the form of trademark symbols. The three symbols that can be used are the circled R (®), the little capital letters TM (™), and the little capital letters SM (℠).

How to type the ® R,™ TM, © C symbols. What do they mean? How to use them in different countries? Don't get sued for misusing! Learn everything about them!

The TM symbol placed next to a mark is meant to put the public on notice that the owner considers that particular mark to be proprietary. In other words, the owner is claiming rights to that mark even if a trademark application has not been filed.

You can use TM in logos, product names, and taglines without formal registration. For example, a local coffee shop branding its logo with TM can signal to competitors that the brand identity is under informal protection. TM provides limited protection under common law, which applies within the geographic area where the mark is used.
