# for character
convertCase(c("Hi", "HEllo", "greaT"), case = "upperFirst")
#> [1] "Hi"    "Hello" "Great"

# for GADSdat
input_g <- import_DF(data.frame(v1 = 1:3, v2 = c("Hi", "HEllo", "greaT"),
                          stringsAsFactors = FALSE))
convertCase(input_g, case = "upperFirst", vars = "v2")
#> $dat
#>   v1    v2
