从另一个表的多个列创建一个表

Question

I have a table ABC with three columns,

Hugo_Symbol   Consequence        Tumor_Sample
AACS        missense_variant    WCMC10362_2_C
AADACL4     missense_variant    WCMC188_1_C
AADACL4     missense_variant    WCMC189_1_C
AADACL4     missense_variant    WCMC10362_2_C
AASS         splice_variant     WCMC10362_2_C
ABCA13      missense_variant    WCMC188_1_C
ABCA13      missense_variant    WCMC10362_2_C

I need to create a new table df1 with the values from the three columns of ABC,

Hugo_Symbol  WCMC188_1_C       WCMC189_1_C      WCMC10362_2_C
AACS         NA                NA               missense_variant
AADACL4    missense_variant   missense_variant  missense_variant        
AASS         NA                NA               splice_variant
ABCA13     missense_variant    NA               missense_variant

I did not find a code that allows me to do this. I can create a structure of the second table as follows if there is a code to enter values into the table.

Hugo_Symbol  WCMC188_1_C       WCMC189_1_C      WCMC10362_2_C
AACS        
AADACL4     
AASS        
ABCA13

Answer 1

a simple spread will do here.

df1 <- df %>%
  spread( key = Tumor_Sample, value = Consequence, fill = NA)  

Answer 2

#You can try with reshape package and the function recast.
library(reshape2)
recast(df1, df1$Hugo_Symbol + variable ~ df1$Tumor_Sample, id.var = 
c("Hugo_Symbol", "Tumor_Sample"))
