[R] Creating New Variable Using Ifelse

Hello R Help List,

I am an R novice and trying to use the ifelse function to create a new binary
variable based off of the responses of two other binary variables; NAs are
involved.  I pulled it off almost successfully, but when I checked the counts of
my new variable for accuracy, I found that a small portion of the NA cases were
not being passed through as NAs, but as "0" counts in my new variable.
My many attempts at creating a nested ifelse statement that would pass the NAs
through properly have not been successful.  Any help is greatly appreciated.

Here is a MRE:?

library(RCurl)
data <-
getURL("https://raw.githubusercontent.com/cbenjamin1821/careertech-ed/master/elsq2wbl.csv")
elsq2wbl <- read.csv(text = data)

##Recoding Negative Responses to NA
elsq2wbl [elsq2wbl[, "EVERRELJOB"] < -3, "EVERRELJOB"]
<- NA
elsq2wbl [elsq2wbl[, "PSWBL"] < -2, "PSWBL"] <- NA

#Labeling categorical variable levels
elsq2wbl$EVERRELJOB <- factor(elsq2wbl$EVERRELJOB, levels = c(0,1), labels =
c("No","Yes"))
elsq2wbl$PSWBL <- factor(elsq2wbl$PSWBL, levels = c(0,1), labels =
c("No","Yes"))

##Trying to create a new variable to indicate if the student had a job
#related to the college studies that was NOT a WBL experience
elsq2wbl$NONWBLRELJOB <- ifelse(elsq2wbl$PSWBL=="No" &
elsq2wbl$EVERRELJOB=="Yes",1,0)

#Cross tab to check counts of two variables that new variable is based upon
xtabs(~PSWBL+EVERRELJOB,subset(elsq2wbl,BYSCTRL==1&G10COHRT==1),addNA=TRUE)

#Checking count of newly created variable
Q2sub <- subset(elsq2wbl,BYSCTRL==1&G10COHRT==1)
library(plyr)
count(Q2sub,'NONWBLRELJOB')

#The new variable has the correct count of "1", but 88 cases too many
for "0"
#The cross tab shows 20 and 68 NA cases that are being incorrectly counted as
"0" in the new variable

#My other approach at trying to handle the NAs properly-returns an error
elsq2wbl$NONWBLRELJOB <- ifelse(elsq2wbl$PSWBL=="No" &
elsq2wbl$EVERRELJOB=="Yes",1,ifelse(is.na(elsq2wbl$PSWBL)&is.na(elsq2wbl$EVERRELJOB),NA,
                                                                                
ifelse(elsq2wbl$PSWBL!="No" &
elsq2wbl$EVERRELJOB!="Yes",0)))

I could not follow the question up clearly. But one thing that come across to my
sight is that you have values in elsq2wbl$EVERRELJOB as below:

summary(factor(elsq2wbl$EVERRELJOB))
  -9   -8   -7   -4   -3    0    1 
 139  459  946 2488 1948 4619 5598 

and in fact, you want to set negative values to NA.
> ##Recoding Negative Responses to NA
> elsq2wbl [elsq2wbl[, "EVERRELJOB"] < -3,
"EVERRELJOB"] <- NA
But after the command, you still have 1948 ?-3' in the variable;

summary(factor(elsq2wbl$EVERRELJOB))
  -3    0    1 NA's 
1948 4619 5598 4032 

So I think, you need to fix the line as follows:
> ##Recoding Negative Responses to NA
> elsq2wbl [elsq2wbl[, "EVERRELJOB"] <= -3,
"EVERRELJOB"] <- NA

Instead of using ?-2' and ?-3' as threshold to set NA for different
variables, why don?t you use ?less than zero? condition as follows?

elsq2wbl [elsq2wbl[, "EVERRELJOB"] < 0, "EVERRELJOB"]
<- NA
elsq2wbl [elsq2wbl[, "PSWBL"] < 0, "PSWBL"] <- NA

Hence, in both columns (variables), values lower than zero will be NA and you
only will have 0, 1 and NA values in the variable as you called ?binary?.

_ifelse_ part:

You have NA?s in both variables. In this circumstances, consider following
ifelse samples (both sides of '&' can be exchanged)

ifelse(TRUE & TRUE, 1, 0) # 1
ifelse(TRUE & FALSE, 1, 0) # 0
ifelse(FALSE & FALSE, 1, 0) # 0
ifelse(TRUE & NA, 1, 0) # NA
ifelse(FALSE & NA, 1, 0) # 0

according to above, try to create new logic to achieve what you need.

In your last neste-ifelse, you forgot to define a value if deepest ifelse
statement fails.

elsq2wbl$NONWBLRELJOB <- ifelse(elsq2wbl$PSWBL=="No" &
elsq2wbl$EVERRELJOB=="Yes", 1,
                                ifelse(is.na(elsq2wbl$PSWBL) &
is.na(elsq2wbl$EVERRELJOB), NA,
                                       ifelse(elsq2wbl$PSWBL != "No"
& elsq2wbl$EVERRELJOB != "Yes",0, "Forgotten value")))

Also, please, try to create a _minimal reproducible example_ instead of make us
download a big csv file (219 columns x 16197 rows) and try to understand what
you are trying to do. :)

Did not work for me probably due to some restriction of data access.

If you wanted recode values below zero to NA you can do this easily without any
ifelse

You can use simple logical functions to get desired result

First sample data> a <- sample(c("Y", "N"), 30, replace=TRUE)
> b <- sample(c("Y", "N"), 30, replace=TRUE)
> (a=="N")*(b=="Y") [1] 1 1 0 0 1 0 0 0 0 0 1 0 0 1 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1

has 1 only if both conditions are met.

and it works with NA values too.
> a[c(3,5,8)] <- NA
> b[c(3,6,7,8)] <- NA
> (a=="N")*(b=="Y") [1]  1  1 NA  0 NA NA NA NA  0  0  1  0  0  1  0  0  0  0  1  0  0  0  0  0  0

[R] Creating New Variable Using Ifelse

Thanks very much; with your tips, I was able to get the nested ifelse statement
to work properly!
