Issues changing color on ggplot using scale_fill_brewer












1















enter image description here



I have a dataframe that I want to plot, where one column is a category and the other is counts.



I used scale_fill_brewer, but it's not changing any colors. The color is also off -- the bars are all neon colored.



How can I fix this?



The dataframe:



> dput(broad_cat)

structure(list(numbs = c(629, 526, 246, 86), labs = structure(c(4L, 

2L, 3L, 1L), .Label = c("Propaganda", "Public Service", "Public Welfare", 

"Social Welfare"), class = "factor")), .Names = c("numbs", "labs"

), row.names = c(NA, -4L), class = "data.frame")


plot code:



p <- ggplot(broad_cat, 

            aes(reorder(broad_cat$labs, -(broad_cat$numbs), sum), 

                broad_cat$numbs))

p +

  geom_bar(stat = "identity", fill = broad_cat$numbs) + 

  labs(x = "Categories", y = "Counts") +

  ggtitle("Title[![enter image description here][1]][1]") + 

  theme(axis.title.x = element_text(size = 9),

        axis.title.y = element_text(size = 9),

        plot.title = element_text(size = 10, hjust = 0.5)) +

  scale_fill_brewer(palette = "Blues")


Fixed:



I included fill in aes(), but the graph is still black and white.



aes(reorder(broad_cat$labs, -(broad_cat$numbs), sum), 

    broad_cat$numbs), fill = broad_cat$numbs)





r ggplot2

Since numbs is numeric with no repeating values, I understand that you use it for fill just to get some nice colors. Otherwise, as the error suggests, it is not going to work as numbs is continuous and your fill scale is discrete. Perhaps the following is what you want:



p <- ggplot(broad_cat, aes(reorder(labs, -numbs, sum), numbs))

p + geom_bar(stat = "identity", aes(fill = as.factor(numbs)), show.legend = FALSE) + 

  labs(x = "Categories", y = "Counts") + 

  ggtitle("Title[![enter image description here][1]][1]") + 

  theme(axis.title.x = element_text(size = 9),

        axis.title.y = element_text(size = 9),

        plot.title = element_text(size = 10, hjust = 0.5)) + 

  scale_fill_brewer(palette = "Blues")


enter image description here



Where the main things were to use fill inside aes, convert numbs to a factor as to use the discrete scale, and also I removed all broad_cat$... as those will lead to problems and variables should be referred to directly by name.

  • @song0089, no problem, I'm glad it helped. And indeed you shouldn't never use $ inside aes and, typically (though not always), there is no need for that elsewhere in the ggplot call either.

Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

Image
28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

Image
up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form?

A Topological Invariant for $pi_3(U(n))$

Image
3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
