Получение общей информации из двух фреймов данных

У меня есть очень большие файлы, такие как 

    > dput(head(big))
structure(list(Tumor_Sample_Barcode = c("LP6005334_DNA_H01", 
"LP6005334_DNA_H01", "LP6005334_DNA_H01", "LP6005334_DNA_H01", 
"LP6005334_DNA_H01", "LP6005334_DNA_H01"), Chromosome = c("chr1", 
"chr1", "chr1", "chr1", "chr1", "chr1"), Start_Position = c(782112, 
1026918, 1133283, 1431511, 1742395, 1864994), Reference_Allele = c("G", 
"C", "C", "G", "C", "G"), Tumor_Seq_Allele2 = c("A", "T", "T", 
"A", "T", "A")), row.names = c("1", "2", "3", "4", "5", "6"), class = "data.frame")

Это включает хромосомную позицию мутаций

Для тех же образцов у меня есть меньший фрейм данных, например

Я хочу извлечь то, что находится в небольшом файле, который является обычным для большого файла, чтобы у меня был маленький файл, вся его информация совместно использовалась с большим файлом

Я пробовал 

merge(small,big)
Error in merge.data.table(small,big) :

x имеет несколько повторяющихся имен столбцов: Interpro_domain. Удалите или переименуйте дубликаты и попробуйте еще раз.

объединить (маленький, большой) 

Error in merge.data.table(small, big) : 
x has some duplicated column name(s): Interpro_domain. Please remove or rename the duplicate(s) and try again.

Я тоже пробовал 

> subset(small, big)
Error in subset.data.table(small, big) : 'subset' must evaluate to logical
> intersect(small, big)
data frame with 0 columns and 0 rows

Пожалуйста, вы может мне помочь

Имена столбцов дублируются в small dataframe, чтобы сделать их уникальными. 

library(data.table)

# merge by tumor by barcode
merge(small, big, by = "Tumor_Sample_Barcode")

# Error in merge.data.table(small, small, by = "Tumor_Sample_Barcode") : 
#   x has some duplicated column name(s): Interpro_domain. Please remove or
#   rename the duplicate(s) and try again.

Как и ожидалось, мы получаем ошибку, "Interpro_domain" дублируется. Определите их и сделайте уникальными 

dupeCols <- colnames(small)[ duplicated(colnames(small)) ]
dupeColsIx <- which(colnames(small) %in% dupeCols)
colnames(small)[ dupeColsIx ] <- make.unique(colnames(small)[ dupeColsIx ])

Давайте снова объединимся: 

merge(small, big, by = "Tumor_Sample_Barcode")

Error in vecseq(f__, len__, if (allow.cartesian || notjoin || !anyDuplicated(f__,  : 
  Join results in 18 rows; more than 9 = nrow(x)+nrow(i). Check for duplicate key values in i each of which join to the same group in x over and over again. If that's ok, try by=.EACHI to run j for each group to avoid the large allocation. If you are sure you wish to proceed, rerun with allow.cartesian=TRUE. Otherwise, please search for this error message in the FAQ, Wiki, Stack Overflow and data.table issue tracker for advice.

Эта ошибка говорит, что значения нашего ключевого столбца "Tumor_Sample_Barcode" дублируются как в big , так и в small , поэтому потенциально мы создадим декартово соединение, если мы уверены, тогда установите аргумент как: 

merge(small, big, by = "Tumor_Sample_Barcode", allow.cartesian = TRUE)

Это работает нормально, но создает 18 строк из 3 и 6 строки данных, возможно, не то, что вам нужно. Либо объедините более чем один столбец, либо удалите дубликат одного из наборов данных.

library("dplyr")
small$Start_Position<-as.numeric(as.character(small$Start_Position))

all_inner<-inner_join(small,big,by=NULL)

Попробуйте merge(big, small, by="Tumor_Sample_Barcode"). Также я не совсем понимаю, что вы хотите получить.
