R Transposing row values to colum

Question

The output of data %>% select(Year, Type) %>% table() give me:

Year  Type Freq
2001    A     5
2002    A     2
2003    A     9
...    ...  ...
2001    B    21   
2002    B    22
2003    B    19

How I would like my data:

Year  A   B   C   D   E  
2001  5  21   ..  ..  ..
2002  2  22   ..  ..  .. 
2003  9  19   ..  ..  ..
...

How can I achieve this? The examples I find don't seem to match my case

Answer 1

A base R option using reshape

reshape(
  df,
  direction = "wide",
  idvar = "Year",
  timevar = "Type"
)

gives

  Year Freq.A Freq.B
1 2001      5     21
2 2002      2     22
3 2003      9     19

A data.table option

dcast(setDT(df), Year ~ Type)

gives

   Year A  B
1: 2001 5 21
2: 2002 2 22
3: 2003 9 19

A dplyr option

df %>%
  pivot_wider(names_from = Type, values_from = Freq)

gives

# A tibble: 3 x 3
   Year     A     B
  <int> <int> <int>
1  2001     5    21
2  2002     2    22
3  2003     9    19

Data

> dput(df)
structure(list(Year = c(2001L, 2002L, 2003L, 2001L, 2002L, 2003L
), Type = c("A", "A", "A", "B", "B", "B"), Freq = c(5L, 2L, 9L,
21L, 22L, 19L)), class = "data.frame", row.names = c(NA, -6L))
