Мы можем использовать dcast
после создания столбца последовательности
library(data.table)
setDT(df1)[, n := seq_len(.N), .(code, Sex)]
dcast(df1, n + offspring ~ rowid(n), value.var = c('parent', 'code', 'Sex', 'Value'), sep = "")
# n offspring parent1 parent2 code1 code2 Sex1 Sex2 Value1 Value2
#1: 1 J44010_CCG7YANXX_2_661_X4 49032 48465 s d M f -0.3845506 0.4340901
#2: 2 J44010_CCG7YANXX_2_661_X4 48741 48521 s d M f 0.1057434 0.4033745
#3: 3 J44010_CCG7YANXX_2_661_X4 48757 48703 s d M f 0.3957291 -0.3814898
В base R
, мы можем использовать reshape
df1$n <- with(df1, ave(seq_along(Sex), Sex, FUN = seq_along))
df1$n1 <- with(df1, ave(n, n, FUN = seq_along))
reshape(df1[-1], idvar = c('n', 'offspring'), timevar = 'n1', direction = 'wide' )
data
df1 <- structure(list(seq = 1:6, parent = c(49032L, 48741L, 48757L,
48465L, 48521L, 48703L), code = c("s", "s", "s", "d", "d", "d"
), Sex = c("M", "M", "M", "f", "f", "f"),
offspring = c("J44010_CCG7YANXX_2_661_X4",
"J44010_CCG7YANXX_2_661_X4", "J44010_CCG7YANXX_2_661_X4",
"J44010_CCG7YANXX_2_661_X4",
"J44010_CCG7YANXX_2_661_X4", "J44010_CCG7YANXX_2_661_X4"),
Value = c(-0.38455056,
0.1057434, 0.39572906, 0.43409006, 0.40337447, -0.3814898)),
class = "data.frame", row.names = c(NA, -6L))
