Convert dataframe column to 1 or 0 for true false values and assign to dataframe

Question

In the R cli I am able to do the following on a character column in a data frame    gt  data frame column name  data frame column name     true    lt - 1  gt  data frame column name  data frame column name     false    lt - 0  gt  data frame column name  lt - as integer data frame column name    I would like to do this as a function and I tried the following code  inputing data frame column name as arg1   I see that it is working when I return arg1  but how do I return the operation to the original data frame   boolean integer  lt - function arg1      arg1  arg1     true    lt - 1   arg1  arg1     false    lt - 0   arg1  lt - as integer arg1

Try this  it will convert True into 1 and False into 0  data frame column name num   lt - as numeric data frame column name   Then you can convert into factor if you want  data frame column name num factor  lt - as  factor data frame column name num

chappers solution  in the comments  works as integer as logical data frame column name

Since you re dealing with values that are just supposed to be boolean anyway  just use    and convert the logical response to as integer   df  lt - data frame col   c  true    true    false    df       col   1  true   2  true   3 false df col  lt - as integer df col     true   df     col   1   1   2   1   3   0

Even when you asked finally for the opposite  to reform 0s and 1s into Trues and Falses  however  I post an answer about how to transform falses and trues into ones and zeros  1s and 0s   for a whole dataframe  in a single line   Example given   df  lt - structure list p1 1   c TRUE  FALSE  FALSE  NA  TRUE  FALSE                   NA   p1 2   c FALSE  TRUE  FALSE  NA  FALSE  NA                   TRUE   p1 3   c TRUE                   TRUE  FALSE  NA  NA  FALSE  TRUE   p1 4   c FALSE  NA                   FALSE   FALSE  TRUE  FALSE  NA   p1 5   c TRUE  NA                   FALSE  TRUE  FALSE  NA  TRUE   p1 6   c TRUE  NA                   FALSE  TRUE  FALSE  NA  TRUE   p1 7   c TRUE  NA                   FALSE  TRUE  NA  FALSE  TRUE   p1 8   c FALSE                   FALSE  NA  FALSE  TRUE  FALSE  NA   p1 9   c TRUE                   FALSE   NA  FALSE  FALSE  NA  TRUE   p1 10   c TRUE                   FALSE  NA  FALSE  FALSE  NA  TRUE   p1 11   c FALSE                   FALSE  NA  FALSE  NA  FALSE  TRUE     Names                    c  p1 1    p1 2    p1 3    p1 4    p1 5    p1 6                     p1 7    p1 8    p1 9    p1 10    p1 11    row names                     c NA  -7L   class    data frame       p1 1  p1 2  p1 3  p1 4  p1 5  p1 6  p1 7  p1 8  p1 9 p1 10 p1 11 1  TRUE FALSE  TRUE FALSE  TRUE  TRUE  TRUE FALSE  TRUE  TRUE FALSE 2 FALSE  TRUE  TRUE    NA    NA    NA    NA FALSE FALSE FALSE FALSE 3 FALSE FALSE FALSE FALSE FALSE FALSE FALSE    NA    NA    NA    NA 4    NA    NA    NA FALSE  TRUE  TRUE  TRUE FALSE FALSE FALSE FALSE 5  TRUE FALSE    NA  TRUE FALSE FALSE    NA  TRUE FALSE FALSE    NA 6 FALSE    NA FALSE FALSE    NA    NA FALSE FALSE    NA    NA FALSE 7    NA  TRUE  TRUE    NA  TRUE  TRUE  TRUE    NA  TRUE  TRUE  TRUE   Then by running that  df   1 all Falses and Trues are trasnformed into 1s and 0s  At least  this was happen in the R version that I have  R version 3 4 4  2018-03-15        gt  df 1   p1 1 p1 2 p1 3 p1 4 p1 5 p1 6 p1 7 p1 8 p1 9 p1 10 p1 11 1    1    0    1    0    1    1    1    0    1     1     0 2    0    1    1   NA   NA   NA   NA    0    0     0     0 3    0    0    0    0    0    0    0   NA   NA    NA    NA 4   NA   NA   NA    0    1    1    1    0    0     0     0 5    1    0   NA    1    0    0   NA    1    0     0    NA 6    0   NA    0    0   NA   NA    0    0   NA    NA     0 7   NA    1    1   NA    1    1    1   NA    1     1     1   I do not know if it a total  safe  command  under all different conditions   dfs

can you try if else   gt  col2 ifelse df1 col   true  1 0   gt  df1  col  1   true    false    gt  cbind df1 col         1      1    true    2    false   gt  cbind df1 col col2               col2  1    true    1    2    false   0
