Inserting a blank row to every other row
...nrow(z)) *2
> z <-rbind(z,z)
> z[i, ] <- matrix(NA, nr=nrow(z),nc=ncol(z))
> z
a b
1 1 a
2 NA <NA>
3 3 c
4 NA <NA>
5 2 b
6 NA <NA>
But I agree with you that there is probably a way to handle the
underlying issues that does not require this kind of artifice.
Cheers,

preparing data for barplot()
What is the best way to produce a barplot from my data? I would like
the barplot to show each person with the values stacked
val1+val2+val3, so there is one bar for each person When I use
barplot(data.matrix(realdata)), it shows one bar for each value
instead.
To post here, I created an artificical data set, but it works fine.
fakedata <- as.data.frame(list(LETTERS[1:3]))
colnames(fakedata)

Inserting a blank row to every other row
Hi Saba,
I don't know how to do what you want and I also cannot see why.
If you describe what you hope to achieve there might be a different
solution.
Best wishes

Inserting a blank row to every other row
Hi
I need to insert a blank row after every row in R data frame. I have achieved it through:
df[rep(1:nrow(df),1,each=2),]
But it inserts a row with name of previous row, while i want a complete blank row without any name/title.
Please guide me
Regards

Prediction with multiple zeros in the dependent variable
I have a batch of data in each line of data contains three values,
calcium score, age, and sex. I would like to predict calcium scores as a
function of age and sex, i.e. calcium=f(age,sex). Unfortunately the
calcium scorers have a very "ugly distribution". There are multiple
zeros, and multiple values between 300 and 600. There are no values
between zero and 300. Needless to say, the
