Dear Camilo,
You can do this:
dat1 <- structure(list(
w = c(TRUE,TRUE,TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE,TRUE,TRUE,TRUE,TRUE),
x = c(NA,NA,NA,NA,NA,NA,NA,NA,NA,NA,NA,NA,NA),
y =
c(FALSE,FALSE,FALSE,FALSE,FALSE,TRUE,TRUE,FALSE,FALSE,TRUE,TRUE,TRUE,FALSE),
z = c(TRUE,TRUE,TRUE,TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,TRUE,TRUE,TRUE,FALSE)),
row.names = c(NA, -13L),
class = "data.frame")
dat1<-t(dat1)
colnames(dat1)<-c("a","b","c","d","e","f","g","h","i","j","k", "l","m")
dat1<- as.data.frame(dat1)
dat2<-dat1
dat2[rowSums(is.na(dat2))==0,]<-
t(apply(!dat1[rowSums(is.na(dat1))==0,],1,function(x)
unlist(lapply(split(x,cumsum(c(0,abs(diff(x))))),cumsum))))
dat2
#?? a? b? c? d? e? f? g? h? i? j? k? l? m
#w? 0? 0? 0? 0? 0? 1? 2? 3? 4? 0? 0? 0? 0
#x NA NA NA NA NA NA NA NA NA NA NA NA NA
#y? 1? 2? 3? 4? 5? 0? 0? 1? 2? 0? 0? 0? 1
#z? 0? 0? 0? 0? 1? 0? 0? 0? 1? 0? 0? 0? 1
Suppose if NAs are there but not for the entire row (if I understand
correctly), you wanted to have the whole row NA, right.
datNew<- structure(list(a = c(TRUE, NA, FALSE, TRUE, TRUE), b = c(TRUE,
NA, FALSE, TRUE, TRUE), c = c(TRUE, NA, FALSE, TRUE, FALSE),
??? d = c(TRUE, NA, FALSE, TRUE, FALSE), e = c(TRUE, NA, FALSE,
??? FALSE, NA), f = c(FALSE, NA, TRUE, TRUE, NA), g = c(FALSE,
??? NA, TRUE, TRUE, TRUE), h = c(FALSE, NA, FALSE, TRUE, FALSE
??? ), i = c(FALSE, NA, FALSE, FALSE, NA), j = c(TRUE, NA, TRUE,
??? TRUE, TRUE), k = c(TRUE, NA, TRUE, TRUE, FALSE), l = c(TRUE,
??? NA, TRUE, TRUE, FALSE), m = c(TRUE, NA, FALSE, FALSE, TRUE
??? )), .Names = c("a", "b", "c", "d", "e", "f", "g", "h", "i",
"j", "k", "l", "m"), row.names = c("w", "x", "y", "z", "u"), class =
"data.frame")
datNew
#????? a???? b???? c???? d???? e???? f???? g???? h???? i??? j????
k???? l???? m
#w? TRUE? TRUE? TRUE? TRUE? TRUE FALSE FALSE FALSE FALSE TRUE? TRUE?
TRUE? TRUE
#x??? NA??? NA??? NA??? NA??? NA??? NA??? NA??? NA??? NA?? NA???

#y FALSE FALSE FALSE FALSE FALSE? TRUE? TRUE FALSE FALSE TRUE? TRUE?
TRUE FALSE
#z? TRUE? TRUE? TRUE? TRUE FALSE? TRUE? TRUE? TRUE FALSE TRUE? TRUE?
TRUE FALSE
#u? TRUE? TRUE FALSE FALSE??? NA??? NA? TRUE FALSE??? NA TRUE FALSE
FALSE? TRUE
dat2New<- datNew
dat2New[rowSums(is.na(dat2New))==0,]<-t(apply(!datNew[rowSums(is.na(datNew))==0,],1,function(x)
unlist(lapply(split(x,cumsum(c(0,abs(diff(x))))),cumsum))))
dat2New[rowSums(is.na(dat2New))!=0 &
rowSums(is.na(dat2New))!=ncol(dat2New),]<-NA
?dat2New
#?? a? b? c? d? e? f? g? h? i? j? k? l? m
#w? 0? 0? 0? 0? 0? 1? 2? 3? 4? 0? 0? 0? 0

Subject: Re: [R] conditional Dataframe filling
Thanks Arun,
Well that is interesting. My intention was to have a dataframe with
the same number of rows in the original data, and for the rows with
NAs, then return NA (If there are NAs, often the entire row has NAs).
What is interesting is that in your code with NAs, the row that has
NAs gets NAs in the output, which is what I am looking for.
I guess a solution is to subset complete rows and then run your line
of code. Unless there is an alternative, to tell cumsum to leave NAs
as NAs?
Thanks again,
Camilo

Dear Camilo,
How do you want to deal with the NAs?
If I remove the NAs:
dat1 <- structure(list(
w = c(TRUE,TRUE,TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE,TRUE,TRUE,TRUE,TRUE),
x = c(NA,NA,NA,NA,NA,NA,NA,NA,NA,NA,NA,NA,NA),
y =
c(FALSE,FALSE,FALSE,FALSE,FALSE,TRUE,TRUE,FALSE,FALSE,TRUE,TRUE,TRUE,FALSE),
z = c(TRUE,TRUE,TRUE,TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,TRUE,TRUE,TRUE,FALSE)),
row.names = c(NA, -13L),
class = "data.frame")
dat1<-t(dat1)
colnames(dat1)<-c("a","b","c","d","e","f","g","h","i","j","k", "l","m")
dat1<- as.data.frame(na.omit(dat1))
dat2<-dat1
dat2[]<-t(apply(!dat1,1,function(x)
unlist(lapply(split(x,cumsum(c(0,abs(diff(x))))),cumsum))))
?dat2
#? a b c d e f g h i j k l m
#w 0 0 0 0 0 1 2 3 4 0 0 0 0
#y 1 2 3 4 5 0 0 1 2 0 0 0 1
#z 0 0 0 0 1 0 0 0 1 0 0 0 1
?dat1
#????? a???? b???? c???? d???? e???? f???? g???? h???? i??? j???
k??? l???? m
#w? TRUE? TRUE? TRUE? TRUE? TRUE FALSE FALSE FALSE FALSE TRUE TRUE
TRUE? TRUE
#y FALSE FALSE FALSE FALSE FALSE? TRUE? TRUE FALSE FALSE TRUE TRUE

#z? TRUE? TRUE? TRUE? TRUE FALSE? TRUE? TRUE? TRUE FALSE TRUE TRUE

Dear Arun,
Thank you very? much for your help with this.I did not know where to
start looking to solve that problem, so I truly appreciate your input.
The line of code you sent seems to work but it duplicates the
results. Do you know why that may happen?
Below is a larger database, to which I apply your line of code.
Thank you very much again,
Camilo

HI,
Just a correction:
:
dat2[]<-t(apply(!dat1,1,function(x)
unlist(lapply(split(x,cumsum(c(0,abs(diff(x))))),cumsum))))
#should also work
A.K.

Hi,
You could try:
dat1<- read.table(text="
a??? b??? c??? d
TRUE? TRUE? TRUE? TRUE
FALSE FALSE FALSE TRUE
FALSE? TRUE? FALSE? FALSE
",sep="",header=TRUE)
dat2<-dat1
?dat2[]<-t(apply(1*!dat1,1,function(x)
unlist(lapply(split(x,cumsum(c(0,abs(diff(x))))),cumsum))))
?dat2
#? a b c d
#1 0 0 0 0
#2 1 2 3 0
#3 1 0 1 2

Subject: [R] conditional Dataframe filling
Hi everyone:
This may be trivial but I just have not been able to figure it out.
Imagine the following dataframe:
a? ?? b? ?? c? ?? d
TRUE? TRUE? TRUE? TRUE
FALSE FALSE FALSE TRUE
FALSE? TRUE? FALSE? FALSE
I would like to create a new dataframe, in which TRUE gets 0 but if
false then add 1 to the cell to the left. So the results for the
example above should be something like:
a? ?? b? ?? c? ?? d
0? ?? 0? ?? 0? ?? 0
1? ?? 2? ?? 3? ?? 0
1? ?? 0? ?? 1? ?? 2
I wonder if you may know?.
Thanks,
Camilo
