How to adjust color palette with customized breaks in tmap?

I would like to plot 1950 world population in density map with tmap package.
And I break the population data into 22 categories manually, and fill with different color for each category.
My code is:

    library(tmap)
    data(World)

    map <- tm_shape(World)+
                  tm_fill("1950", 
                  title = "Population class",
                  breaks = c(0, 100 ,200, 300, 400, 500, 600, 700, 800, 900,
                             1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800,
                             1900, 2000, 3000, 4000),
                  textNA = "No data",
                  colorNA = "white", 
                  palette = "topo")+
              tm_borders()+
              tm_layout("World Density Population Map")
              tm_style_classic()
    current.mode <- tmap_mode("plot")
    map  

And error occurred at the last step "map":

Error: Invalid palette

I had a public dataset from wpp2015 which is not exactly same as my dataset but will provide an intuition of my data frame structure.

     dput(df) <- structure(list(name = structure(c(1L, 3L, 4L, 5L, 6L, 14L, 7L, 11L, 13L, 15L, 16L, 17L, 8L, 18L, 20L, 23L, 24L, 25L, 26L, 27L, 21L, 190L, 28L, 29L, 146L, 31L, 19L, 33L, 34L, 35L, 32L, 37L, 201L, 40L, 42L, 43L, 46L, 47L, 48L, 134L, 49L, 58L, 50L, 52L, 53L, 55L, 56L, 22L, 59L, 61L, 65L, 67L, 68L, 71L, 69L, 70L, 73L, 74L, 75L, 76L, 77L, 60L, 78L, 80L, 79L, 203L, 81L, 82L, 108L, 83L, 84L, 85L, 86L, 87L, 88L, 90L, 91L, 93L, 44L, 94L, 95L, 96L, 97L, 98L, 99L, 100L, 101L, 102L, 51L, 103L, 104L, 106L, 105L, 107L, 57L, 173L, 109L, 110L, 111L, 115L, 116L, 113L, 119L, 120L, 121L, 124L, 45L, 125L, 126L, 127L, 128L, 129L, 130L, 131L, 132L, 133L, 136L, 141L, 174L, 142L, 144L, 145L, 160L, 147L, 148L, 149L, 54L, 9L, 150L, 231L, 151L, 152L, 153L, 154L, 158L, 138L, 162L, 163L, 164L, 165L, 166L, 167L, 168L, 170L, 89L, 214L, 171L, 172L, 175L, 176L, 177L, 178L, 179L, 202L, 181L, 182L, 183L, 184L, 185L, 186L, 187L, 188L, 233L, 189L, 191L, 194L, 241L, 200L, 196L, 205L, 237L, 206L, 207L, 208L, 209L, 210L, 211L, 213L, 215L, 216L, 217L, 223L, 218L, 219L, 220L, 221L, 222L, 212L, 66L, 224L, 41L, 225L, 226L, 227L, 30L, 229L, 230L, 232L, 180L, 239L, 240L, 238L, 143L, 117L, 2L, 112L, 156L, 63L, 72L, 159L, 62L, 140L, 155L, 197L, 234L, 36L, 38L, 193L, 192L, 235L, 64L, 157L, 199L, 236L, 12L, 135L, 195L, 161L, 10L, 114L, 204L, 118L, 137L, 169L, 122L, 123L, 228L, 92L, 139L, 39L, 198L), .Label = c("Afghanistan", "Africa", "Albania", "Algeria", "Angola", "Antigua and Barbuda", "Argentina", "Armenia", "Aruba", "Asia", "Australia", "Australia/New Zealand", "Austria", "Azerbaijan", "Bahamas", "Bahrain", "Bangladesh", "Barbados", "Belarus", "Belgium", "Belize", "Benin", "Bhutan", "Bolivia (Plurinational State of)", "Bosnia and Herzegovina", "Botswana", "Brazil", "Brunei Darussalam", "Bulgaria", "Burkina Faso", "Burundi", "Cabo Verde", "Cambodia", "Cameroon", "Canada", "Caribbean", "Central African Republic", "Central America", "Central Asia", "Chad", "Channel Islands", "Chile", "China", "China, Hong Kong SAR", "China, Macao SAR", "China, Taiwan Province of China", "Colombia", "Comoros", "Congo", "Costa Rica", "Cote d'Ivoire", "Croatia", "Cuba", "Curacao", "Cyprus", "Czech Republic", "Dem.

I appreciate if anyone could help.

Assuming that you are using the World dataset from the tmap package. There are three issues with your code. First, there are no column called 1950. The column indicating to population density is pop_est_dens. Second, assuming that pop_est_dens is the column you want to plot, the breaks is too large as the maximum is only about 1200. Third, topo is not a valid palette name.

Therefore, I modified your code as follows.

library(tmap)
data(World)

map <- tm_shape(World)+
  tm_fill("pop_est_dens", 
          title = "Population class",
          breaks = c(0, 100 ,200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200),
          style = "fixed",
          textNA = "No data",
          colorNA = "white", 
          palette = "Reds")+
  tm_borders() +
  tm_layout("World Density Population Map")
map

Is it possible to add fixed breaks to a size variable in a tm_bubble() plot?Gladstone
@spacedSparking This question seems to be unrelated to tm_bubble.Gabfest
Good point. I've created a new question regarding this here.Gladstone
