I want to create a column CONUM which is the total number of values other than zero in the CO column for each value in the ID column. So for example the CO column for ID 1 has 3 values other than zero, therefore the corresponding values in CONUM column is 3. The MV column is 0 if CO column has a value and 1 if CO column is 0. So another way to accomplish creating the CONUM column would be to count the number of zeros per ID . It would be great if you could help me with the r code to accomplish this. Thanks.
Here is an option with data.table
library(data.table)
setDT(df)[,CONUM:=sum(CO!=0) ,ID][]
You can use ave in base R:
dat <- transform(dat, CONUM = ave(as.logical(CO), ID, FUN = sum))
and an option with dplyr
# install.packages("dplyr")
library(dplyr)
dat <- dat %>%
group_by(ID) %>%
mutate(CONUM = sum(CO != 0))

df <- data.frame (id = c(1,1,1,2,2,2,3,3,3,3,4,4,4,4,4,4),
qresult=c(0,0,0,0,1,0,0,0,1,0,1,0,0,0,0,0),
count=c(0,0,0,0,1,2,0,0,1,2,1,2,3,4,5,6))
> df

What would be a way to obtain the count column which begins counting when the condition, q_result==1 is met and resets for each new id?
We could wrap with double cumsum on a logical vector after grouping
library(dplyr)
df %>%
group_by(id) %>%
mutate(count2 = cumsum(cumsum(qresult))) %>%
ungroup
-output
# A tibble: 16 × 4
id qresult count count2
<dbl> <dbl> <dbl> <dbl>

I am currently working with survey data in R studio. I originally had two csv files but I merged them into one. Both CSV files contained sample IDs. The first file also contains bivariate info, while the second contains rating as a continuous variable.
Here is a sample of the data
ID O1 O2 O3 O4 O5 O6 O7 O8 S1 S2 S3 S4 S5 S6 S7 S8
22 0 1 0 1 0 1 0 1 4 6 2 6 4 3 6 2
23 0 1 0 0 1 1 0 1 5 6 10 4 5 7 7 6
24 0 1 1 0 1 0 0 1 7 4 7 8 7 6 3 9
25 0 0 1 1 0 0 1 1 3 5 5 7 4 6.9 6 5
26 0 1 0 0 1 1 0 1 2 2.5 7 5 4 5 4 3
27 0 1 1 1 0 1 0 0 6 3 4 6 5 6 5 6
28 0 1 1 1 0 0 0 1 7 4 2 8 2 1 4 5
29 0 0 1 0 1 1 1 0 2 5 1 2 4 3 2 2
30 0 1 0 1 1 1 0 0 8 2 6 7 1 7 5 4
31 0 0 0 1 0 1 1 1 7 4 3 2 4 5 7 2
32 0 0 1 0 0 1 1 1 4 7 5 3 1 6 2 3
33 0 1 1 0 1 1 0 0 7 4 5 8 8 5 6 7
For example the 0 in O1 corresponds to the 4 in S1.
I want to make a loop that will sum all of the values corresponding to variable 0 and 1.
if value in O1 is 0, add value in S1 to "sum of 0"
if value in O1 is 1, add value in S1 to "sum of 1"
repeat for all columns to get a total value for 0 and 1.
Any strategies or tips would be helpful going forward!
I am trying to use a package where the table they've used is in a certain format, I am very new to R and don't know how to get my data in this same format to be able to use the package.
Their table looks like this:
Recipient
Actor 1 10 11 12 2 3 4 5 6 7 8 9
1 0 0 0 1 3 1 1 2 3 0 2 6
10 1 0 0 1 0 0 0 0 0 0 0 0
11 13 5 0 5 3 8 0 1 3 2 2 9
12 0 0 2 0 1 1 1 3 1 1 3 0
2 0 0 2 0 0 1 0 0 0 2 2 1
3 9 9 0 5 16 0 2 8 21 45 13 6
4 21 28 64 22 40 79 0 16 53 76 43 38
5 2 0 0 0 0 0 1 0 3 0 0 1
6 11 22 4 21 13 9 2 3 0 4 39 8
7 5 32 11 9 16 1 0 4 33 0 17 22
8 4 0 2 0 1 11 0 0 0 1 0 1
9 0 0 3 1 0 0 1 0 0 0 0 0
Where mine at the moment is:
X0 X1 X2 X3 X4 X5
0 0 2 3 3 0 0
1 1 0 4 2 0 0
2 0 0 0 0 0 0
3 0 2 2 0 1 0
4 0 0 3 2 0 2
5 0 0 3 3 1 0
I would like to add the recipient and actor to mine, as well as change to row and column names to 1, ..., 6.
Also my data is listed under Data in my Workspace and it says:
'num' [1:6,1:6] 0 1 ...
Whereas the example data in the workspace is shown in Values as:
'table' num [1:12,1:12] 0 1 13 ...
Please let me know if you have suggestion to get my data in the same type and style as theirs, all help is greatly appreciated!
OK, so you have a matrix like so:
m <- matrix(c(1:9), 3)
rownames(m) <- 0:2
colnames(m) <- paste0("X", 0:2)
# X0 X1 X2
#0 1 4 7
#1 2 5 8
#2 3 6 9
First you need to remove the Xs and turn it into a table:
colnames(m) <- sub("X", "", colnames(m))
m <- as.table(m)
# 0 1 2
#0 1 4 7
#1 2 5 8
#2 3 6 9
Then you can set the dimension names:
names(dimnames(m)) <- c("Actor", "Recipient")
# Recipient
#Actor 0 1 2
# 0 1 4 7
# 1 2 5 8
# 2 3 6 9
However, usually you would create the contingency table from raw data using the table function, which would automatically return a table object. So, maybe you should fix the step creating your matrix?
I have a question regarding creating new columns if a certain value appears in an existing row.
N=5
T=5
time<-rep(1:T, times=N)
id<- rep(1:N,each=T)
dummy<- c(0,0,1,1,0,0,0,1,0,0,0,1,0,1,0,0,0,0,0,0,1,0,0,1,0)
df <- data.frame(id, time, dummy)
id time dummy
1 1 1 0
2 1 2 0
3 1 3 1
4 1 4 1
5 1 5 0
6 2 1 0
7 2 2 0
8 2 3 1
9 2 4 0
10 2 5 0
11 3 1 0
12 3 2 1
13 3 3 0
14 3 4 1
15 3 5 0
16 4 1 0
17 4 2 0
18 4 3 0
19 4 4 0
20 4 5 0
21 5 1 1
22 5 2 0
23 5 3 0
24 5 4 1
25 5 5 0
In this case we have some cross-sections in which more than one 1 appears. Now I try to create a new dummy variable/column for each additional 1. After that, for each dummy, the rows for each cross-section should also be filled with a 1 after the first 1 appears. I can fill the rows by using group_by(id) and the cummax function on each column. But how do I get new variables without going through every cross-section manually? So I want to achieve the following:
id time dummy dummy2
1 1 1 0 0
2 1 2 0 0
3 1 3 1 0
4 1 4 1 1
5 1 5 1 1
6 2 1 0 0
7 2 2 0 0
8 2 3 1 0
9 2 4 1 0
10 2 5 1 0
11 3 1 0 0
12 3 2 1 0
13 3 3 1 0
14 3 4 1 1
15 3 5 1 1
16 4 1 0 0
17 4 2 0 0
18 4 3 0 0
19 4 4 0 0
20 4 5 0 0
21 5 1 1 0
22 5 2 1 0
23 5 3 1 0
24 5 4 1 1
25 5 5 1 1
Thanks! :)
You can use cummax and you would need cumsum to create dummy2
df %>%
group_by(id) %>%
mutate(dummy1 = cummax(dummy), # don't alter 'dummy' here we need it in the next line
dummy2 = cummax(cumsum(dummy) == 2)) %>%
as.data.frame() # needed only to display the entire result
# id time dummy dummy1 dummy2
#1 1 1 0 0 0
#2 1 2 0 0 0
#3 1 3 1 1 0
#4 1 4 1 1 1
#5 1 5 0 1 1
#6 2 1 0 0 0
#7 2 2 0 0 0
#8 2 3 1 1 0
#9 2 4 0 1 0
#10 2 5 0 1 0
#11 3 1 0 0 0
#12 3 2 1 1 0
#13 3 3 0 1 0
#14 3 4 1 1 1
#15 3 5 0 1 1
#16 4 1 0 0 0
#17 4 2 0 0 0
#18 4 3 0 0 0
#19 4 4 0 0 0
#20 4 5 0 0 0
#21 5 1 1 1 0
#22 5 2 0 1 0
#23 5 3 0 1 0
#24 5 4 1 1 1
#25 5 5 0 1 1
I have a dataframe with many rows, but the structure looks like this:
year factor
1 0
2 0
3 0
4 0
5 0
6 0
7 0
8 0
9 1
10 0
11 0
12 0
13 0
14 0
15 0
16 0
17 1
18 0
19 0
20 0
I would need to add a counter as a third column. It should count the cumulative cells that contains zero until it set again to zero once the value 1 is encountered. The result should look like this:
year factor count
1 0 0
2 0 1
3 0 2
4 0 3
5 0 4
6 0 5
7 0 6
8 0 7
9 1 0
10 0 1
11 0 2
12 0 3
13 0 4
14 0 5
15 0 6
16 0 7
17 1 0
18 0 1
19 0 2
20 0 3
I would be glad to do it in a quick way, avoiding loops, since I have to do the operations for hundreds of files.
You can copy my dataframe, pasting the dataframe in "..." here:
dt <- read.table( text="...", , header = TRUE )
Perhaps a solution like this with ave would work for you:
A <- cumsum(dt$factor)
ave(A, A, FUN = seq_along) - 1
# [1] 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 0 1 2 3
Original answer:
(Missed that the first value was supposed to be "0". Oops.)
x <- rle(dt$factor == 1)
y <- sequence(x$lengths)
y[dt$factor == 1] <- 0
y
# [1] 1 2 3 4 5 6 7 8 0 1 2 3 4 5 6 7 0 1 2 3
