Hello,
Sorry, I didn't understand that 1 and 2 are the final values, I thought
they would be counts of PLATE. I have changed the auxiliary column
'counts' to 'flag'.
mc %>%
group_by(PLATE) %>%
mutate(flag = 2) %>%
pivot_wider(
id_cols = c("FID", "IID"),
names_from = "PLATE",
values_from = flag,
values_fill = list(flag = 1)
)
Hope this helps,
Rui Barradas

Hello,
Something like this?
mc <- read.table(text = "
FID IID PLATE
1 fam0110 G110 4RWG569
2 fam0113 G113 cherry
3 fam0114 G114 cherry
4 fam0117 G117 4RWG569
5 fam0118 G118 5XAV049
6 fam0119 G119 cherry
", header = TRUE)
library(dplyr)
library(tidyr)
mc %>%
group_by(PLATE) %>%
mutate(counts = n()) %>%
pivot_wider(
id_cols = c("FID", "IID"),
names_from = "PLATE",
values_from = counts,
values_fill = list(counts = 0)
)
Hope this helps,

Hello,
I have a data frame like this:
head(mc)
FID IID PLATE
1 fam0110 G110 4RWG569
2 fam0113 G113 cherry
3 fam0114 G114 cherry
4 fam0117 G117 4RWG569
5 fam0118 G118 5XAV049
6 fam0119 G119 cherry
...
dim(mc)
[1] 1625 4
length(unique(mc$PLATE))
[1] 34
I am trying to make a new data frame which would look like this:
FID IID PLATE 4RWG569 cherry 5XAV049 ...
1 fam0110 G110 4RWG569 2 1 1
2 fam0113 G113 cherry 1 2 1
3 fam0114 G114 cherry 1 2 1
4 fam0117 G117 4RWG569 2 1 1
5 fam0118 G118 5XAV049 2 1 1
6 fam0119 G119 cherry 1 2 1
...
so the new data frame would have an additional 34 columns (for every
unique mc$PLATE) and if in the row of PLATE column the value is ==to
that column name I would have 2 otherwise 1
I tried to do this with:
library(reshape2)
m2=dcast(mc, IID ~ PLATE)
Using PLATE as value column: use value.var to override.
Please advise,
Ana
