Hi Ed
You can access the Windows clipboard under Cygwin.
I ran R within Cygwin.
I was able to use read.table (file="clipboard") for both plain text and
Excel tables.

At the point where you say "date difference in days" IMO you have departed from
what `difftime` is for and are in the realm of a numeric measure. I ignore the
units inside `difftime` at all times and convert to numeric with a units
argument if I want to be that specific about how the measure is
You can use units<- to change the time units of the difference. E.g.,
> d <- as.POSIXlt("2018-03-10") - as.POSIXlt("2018-03-09 02:00:00")
> d
Time difference of 22 hours
> units(d) <- "days"
> d
Time difference of 0.917 days
>
> units(d) <- "mins"
> d
Time difference of 1320 mins
> units(d)
ed <- as.POSIXlt("2018-03-10")
sd <- as.POSIXlt("2018-02-10")
as.numeric(ed-sd)
[1] 28
ed <- as.POSIXlt("2000-03-10")
sd <- as.POSIXlt("2000-02-10")
as.numeric(ed-sd)
[1] 29

I have a function to calculate a date difference in days but my results come
back in hours. I suspect I am using the as.POSIXlt function incorrectly .
Suggestions?
# Start time of data to be considered
start_day <- "2016-04-30"
# Make event and sequence IDs into factors
elapsed_days
Dear Agostino
I am afraid this list is an English language one but I suggest that as
well as trying to translate your message you post on the list which
specialises in this sort of thing

where they may be better able to help you.

Morning Bill, I take it this is dplyr? You might try:
tmp1 <- HCPC %>%
group_by(HCPCSCode)
This list is for Help and usually expects you to first show us your own

Generally more efficient to filter before grouping.
Note that summarize clears out
Generally more efficient to filter before grouping.
Note that summarize clears out whatever isn't mentioned in it, so the
subsetting currently being done in the mean call could also be done in the
pre-filter step and you can avoid filtering other columns and then discarding
them by limiting
Morning Bill, I take it this is dplyr? You might try:
tmp1 <- HCPC %>%
group_by(HCPCSCode) %>%
summarise(Avg_AllowByLimit =
mean(Avg_AllowByLimit[which(Avg_AllowByLimit!=0 & AllowByLimitFlag ==
TRUE)]))
The code above gives "NaN" for cases where AllowByLimitFlag == FALSE.
Maybe this is the
Thank you Rui, but that is getting me the overall mean not the mean of just the
observations that are flagged as TRUE Grouped By the HCPCSCode
(AllowByLimitFlag == TRUE).
I also tried adding it to the filter you suggested but that does not seem to
work either?
tmp1 <- tmp %>%
Hello,
Maybe filter the AllowByLimitFlag values first (not tested)?
tmp1 <- tmp %>%
group_by(HCPCSCode) %>%
filter(AllowByLimitFlag) %>%
summarise(Avg_AllowByLimit =
mean(Avg_AllowByLimit[which(Avg_AllowByLimit!=0)]))
Hope this helps,

What Duncan says, but in case you are feeling adventurous or have strong
reasons to be in the Cygwin parallel universe, notice that the error indicates
that R is loooking for an X11 display.
So, at a minimum, you need to have

(b) R setup so that it knows how
