I have this df, and I want to make four new columns:

cuadri

conforme

AQ

n

1

FALSE

2a HTR

1

1

FALSE

3a HMI

1

1

FALSE

PB HTR

1

1

FALSE

Pediatria

1

1

FALSE

PV

4

1

TRUE

2a HTR

8

1

TRUE

3a HMI

9

[...]

2p

FALSE

2a HTR

5

2p

FALSE

3a HMI

7

2p

FALSE

4a HG

7

2p

FALSE

8a HG

4

2p

FALSE

Arritmias

1

2p

FALSE

PB HTR

7

2p

FALSE

Pediatria

4

c1t: If 'cuadri' is 1 AND 'conforme' is true, this cell is the value in 'n'

c1f: If 'cuadri' is 1 AND 'conforme' is false, this cell is the value in 'n'

c2t: If 'cuadri' is 2 AND 'conforme' is true, this cell is the value in 'n'

c2f: If 'cuadri' is 2 AND 'conforme' is false, this cell is the value in 'n'

For example, with AQ=2a HTR,

would have c1f=1, c1t=8, c2f=5 and c2t=8

I tried with mutate and ifelse, but I haven't got it:
AQsum2<-AQsum %>%
mutate(c1t=ifelse(cuadri==1 & conforme==TRUE,AQsum$n,"")) %>%
mutate(c1f=ifelse(cuadri==1 & conforme==FALSE,AQsum$n,"")) %>%
mutate(c2t=ifelse(cuadri=="2p" & conforme==TRUE,AQsum$n,"")) %>%
mutate(c2f=ifelse(cuadri=="2p" & conforme==FALSE,AQsum$n,""))
How I can do it?
Thanks

In R tables all values in a column must be numeric or strings (not mixed).
You don't mention what error you encountered but adapting your solution in the following way, works for me:

library(dplyr)
#>
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#>
#> filter, lag
#> The following objects are masked from 'package:base':
#>
#> intersect, setdiff, setequal, union
library(magrittr)
AQsum <- data.frame(
cuadri = c("1","1", "2p","2p"),
conforme = c(F,T,F,T),
AQ = rep("2a HTR",4),
n = c(1,8,5,8)
)
AQsum %>%
mutate(
c1t = ifelse(cuadri == "1" & conforme == T, n, -999) ,
c1f = ifelse(cuadri == "1" & conforme == F, n, -999) ,
c2t = ifelse(cuadri == "2p" & conforme == T, n, -999) ,
c2f = ifelse(cuadri == "2p" & conforme == F, n, -999)
) %>%
print()
#> cuadri conforme AQ n c1t c1f c2t c2f
#> 1 1 FALSE 2a HTR 1 -999 1 -999 -999
#> 2 1 TRUE 2a HTR 8 8 -999 -999 -999
#> 3 2p FALSE 2a HTR 5 -999 -999 -999 5
#> 4 2p TRUE 2a HTR 8 -999 -999 8 -999
