Thanks for your suggestion. I received a few error messages. Can anyone help
me figure out why I get the following error messages and how to solve them
by revising my code? The data is shown in the post above. Thanks.

Hi thanks for quick reply. I am new to using R and still tried to figure out
how to use Zoo package.
Here is the code I have so far:
library(zoo)
colClasses <- c("NULL", "character", "character", "numeric", "character",
"character", "NULL")
col.names <- c(NA, "webpage", "item", "value", "day",

Thank you very much. I learned a lot through your help. It worked great for
the sample data. But when I try to apply the command to my dataset, I ran
into two more problems.
First, the dataset is huge, it has thousands of lines. I can read it in R.
Using Lines <- " data " may not work such a

Thank you very much. It worked great with the testdata. I have one more
questionto to ask. As my data is incomplete, sometimes Thu is also missing,
then I have no other options but to pick Sat instead, and if Sat is also
missing, then my best possible option is to pick Wed, and etc. Bascially I

I am new to Using R for data analysis. I have an incomplete time series
dataset that is in daily format. I want to extract only Friday data from it.

First, if Friday data is missing in that week, I need to extract the data of
the day prior to that Friday
