R Faites pivoter une seule colonne pour placer les données sur une ligne

Je voudrais prendre une colonne et la faire pivoter pour avoir une seule ligne de données. Actuellement, j'ai deux colonnes et je veux que la seconde soit placée sur une seule ligne

Data:

structure(list(Specimen.Number.Full = structure(c(73L, 73L, 1L, 
1L, 1L, 1L, 1L, 3L, 3L, 3L),.Label = c("CN000007S/22", "CN000009Z/22",

7L, 8L, 14L, 15L, 16L), class = "data.frame")

Code R j'ai:

MSI.Secondary %>%
pivot_wider(names_from = Secondary.Code,values_from = Secondary.Code )

Sortie désirée:

| Specimen.Number.Full | Code.secondaire |

| -------------------- | -------------- |

| PR011196J/22 | M81406|

| PR000048H/22 | M81403| P97008 |

Sortie que j'obtiens :

| Specimen.Number.Full | Code.secondaire |

| -------------------- | -------------- |

| PR011196J/22 | ND | ND | ND | ND | ND | M81406 |

| PR000048H/22 | M81403 | P97008 | ND | ND | ND | ND |


Solution du problème

En utilisant group_by+ summarise, vous pouvez faire :

library(dplyr)
MSI.Secondary |>
group_by(Specimen.Number.Full) |>
summarise(Secondary.Code = paste(Secondary.Code, collapse = ", "))
#> # A tibble: 3 × 2
#> Specimen.Number.Full Secondary.Code
#> <fct> <chr>
#> 1 CN000007S/22 P30852, P30871, P30898, MM0018, P30890
#> 2 CN000014B/22 P30852, P30871, P30897
#> 3 PR000048H/22 M81403, P97008
