Arguments

suffix	a single character string (optional) to attach as a suffix to column names (default NULL)
ind_suffix	an integer vector (optional) that picks the specific columns to attach the suffix (default NULL)

Value

a modified character vector of names that have been lower and caterpillar cased, perhaps with an optional suffix attached

Examples

df_foo = iris

df_foo %>% colname_zen()
df_foo %>% colname_zen(.,suffix="src_1")
df_foo %>% colname_zen(.,suffix="src_1",c(1,5))

# assign names to original data frame
names_new = df_foo %>% colname_zen(.,suffix="src_1",c(1,5))
names(df_foo) = names_new
names(df_foo)

# use ?grepl() to pick col indices
names(df_foo)
ind_grep = which(grepl(names(df_foo),pattern=".Width"))
names_new_grep = df_foo %>% colname_zen(.,suffix="src_1",ind_grep)
names(df_foo) = names_new_grep
