Finding Highest value in groups
Assuming your dataframe is in a variable x:

Finding Highest value in groups
Hi
I have two columns in data frame. First column is based on "ID" assigned to each group of my data (similar ID depicts one group). From second column, I want to identify highest value among each group and want to assign the same ID to that highest value.
Right now the data looks like:
ID Value
1 0.69
1 0.31
2 0.01
2 0.99
3 1.00
4 NA

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
Saba

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

Dividing rows in groups
Hi
I have two data frames as shown below (second one is obtained by aggregating rows of similar IDs in df1.). They both have similar number of columns but rows of df2 are lesser than rows of df1.
df1:
ID A B
1 1 2
1 0 3
2 5 NA
2 1 3
3 1 4
4 NA NA

Descriptive Statistics of time series data
Hi
I have four variables and the time series data for each variable consists of values for past 10 years on monthly basis. I want to get descriptive stats for these four variables separately (mean, median, sd, min, max).
The data I import to R consists of different columns, where each column gives values for one month of a particular year (e.g. March 31st, 2010). Right now R gives descriptive

working with unequal rows
Hi
I have a data frame with rows specifying companies (codes are assigned to companies) and columns specify months (monthly data). The data is based on male (M) and female (F) information for each month. Following is an example of how my data looks like:

001 M M M na
001 F M M M
002 M na F F
003 F F F M
003 F F M na
