Error in UseMethod("select") and Error in ggplot, object 'viz' not found

Just yesterday select was working just fine on the top half of the code but not that is not working.

# pulling libraries
library('dplyr')
library('ggplot2')

# reading the data
data <- read.csv('week2_dataset.csv')

#looking at the data
data

#viewing the data in a more pretty way
View(data)

#selecting variables
data %>%
  #selecting the variable, group, total, and insured columns
  select (variable, group, total, insured, uninsured) %>%
  #filtering by race age and sex, my 3 picked variables
  filter(variable %in% c('race', 'age', 'sex')) %>%
  mutate(percent_insured = insured / total) %>%
  mutate(percent_uninsured = uninsured / total) %>%
mutate(least_insured = ifelse (percent_insured <0.9, 1, 0)) %>%
  mutate (most_insured = ifelse (percent_insured >0.9, 1, 0)) %>%
  mutate (most_least = ifelse (least_insured  <0.9, "most", "least"))
print(data)

data
ggplot(data = viz,
       aes (x = group, y = insured)) +
  geom_col() +
  geom_text(vjust = -1)

The bottom half I can't get ggplot to work.

Here is some troubleshooting data:

dput(head(data)) 
structure(c("function (..., list = character(), package = NULL, lib.loc = NULL, ", 
"    verbose = getOption(\"verbose\"), envir = .GlobalEnv, overwrite = TRUE) ", 
"{", "    fileExt <- function(x) {", "        db <- grepl(\"\\\\.[^.]+\\\\.(gz|bz2|xz)$\", x)", 
"        ans <- sub(\".*\\\\.\", \"\", x)"), dim = c(6L, 1L), dimnames = list(
    c("1", "2", "3", "4", "5", "6"), ""), class = "noquote")
>

Thank you for the help! extremely novice r-studio user here.

First, You don't need to use the mutate function multiple times. you can simply create a variable, and then just add a comma (,) and create another variable.

Second, You did not assign all these changed back to data. you need to start all this big changes pipeline with a 'data <-'.

Lastly, I could'nt make use of your dummy code so i didnt check it myself, but try to get rid of the geom_text (In most cases you should have a label argument with it). Solve the assigning part + get rid of the text, and see if it works. Otherwise code looks just fine :)
