number of rows of result is not a multiple of vector length (arg 2) in R

Question

I have new question related with this my topic deleting outlier in r with account of nominal var. In new case variables x and x1 has different lenght

x <- c(-10, 1:6, 50)
x1<- c(-20, 1:5, 60)
z<- c(1,2,3,4,5,6,7,8)

bx <- boxplot(x)
bx$out

bx1 <- boxplot(x1)
bx1$out


x<- x[!(x %in% bx$out)]
x1 <- x1[!(x1 %in% bx1$out)]


x_to_remove<-which(x %in% bx$out)
x <- x[!(x %in% bx$out)]

x1_to_remove<-which(x1 %in% bx1$out)
x1 <- x1[!(x1 %in% bx1$out)]

z<-z[-unique(c(x_to_remove,x1_to_remove))]
z  

data.frame(cbind(x,x1,z))

then i get the warning

Warning message:
In cbind(x, x1, z) :
  number of rows of result is not a multiple of vector length (arg 2)

so in new dataframe the obs. of Z is not corresponding to x and x1. How can i decide this problem? This solustion is not help me Rsolnp: In cbind(temp, funv) : number of rows of result is not a multiple of vector length (arg 1) or i just do anything wrong.

Edit

x_to_remove<-which(x %in% bx$out)
x <- x[!(x %in% bx$out)]

x1_to_remove<-which(x1 %in% bx1$out)
x1 <- x1[!(x1 %in% bx1$out)]

z<-z[-unique(c(x_to_remove,x1_to_remove))]
z  

d=data.frame(cbind(x,x1,z))
d

it is wrong Warning message:

In cbind(x, x1, z) :
  number of rows of result is not a multiple of vector length (arg 2)

d

  x x1 z
1 1  1 2
2 2  2 3
3 3  3 4
4 4  4 5
5 5  5 6
6 6  1 2

How on this 3 columg get this output

Na  Na  Na
1   1   2
2   2   3
3   3   4
4   4   5
5   5   6
Na  Na  Na
Na  Na  Na

the six row (d) is superfluous

Answer 1

Differents lengths in original x, x1 and z lists is the first problem, how can you say which z values is related to each x and x1 values?

x <- c(-10, 1:6, 50)
x1<- c(-20, 1:5, 60)
z<- c(1,2,3,4,5,6,7,8)
length(x)
[1] 8
length(x1)
[1] 7
length(z)
[1] 8

Another problem is here:

x<- x[!(x %in% bx$out)] #remove this
x1 <- x1[!(x1 %in% bx1$out)] #remove this


x_to_remove<-which(x %in% bx$out)
x <- x[!(x %in% bx$out)]

x1_to_remove<-which(x1 %in% bx1$out)
x1 <- x1[!(x1 %in% bx1$out)]

You clean x and x1 before calculating x_to_remove and x1_to_remove

EDIT: To achieve your desired output try this code (/ode lines added signed in comments):

x <- c(-10, 1:6, 50)
x1<- c(-20, 1:5, 60)
z<- c(1,2,3,4,5,6,7,8)

length_max<-min(length(x),length(x1),length(z)) #Added: identify max length before outlier detection

bx <- boxplot(x)
bx1 <- boxplot(x1)

x_to_remove<-which(x %in% bx$out)
x <- x[!(x %in% bx$out)]

x1_to_remove<-which(x1 %in% bx1$out)
x1 <- x1[!(x1 %in% bx1$out)]

z<-z[-unique(c(x_to_remove,x1_to_remove))]

length_min<-min(length(x),length(x1),length(z)) #Minimum length after outlier remove

d=data.frame(cbind(x[1:length_min],x1[1:length_min],z[1:length_min])) #Bind columns
colnames(d)<-c("x","x1","z")

d_NA<-as.data.frame(matrix(rep(NA,(length_max-length_min)*3),nrow=(length_max-length_min))) #Create NA rows
 colnames(d_NA)<-c("x","x1","z")

d<-rbind(d,d_NA) #Your desired output
d
   x x1  z
1  1  1  2
2  2  2  3
3  3  3  4
4  4  4  5
5  5  5  6
6 NA NA NA
7 NA NA NA
