Hello, helpeRs, I am attempting to reshape (either base R or package reshape) multiple .csv spreadsheets from a very unfortunate wide format to long format. ?Each spreadsheet looks something like this, after being read in to R: toy <- data.frame(year = rep(2007:2008,each = 20), month = rep(1:5,each = 4, length = 40), day = rep(1:2,each = 2,length = 40), hhmm = rep(1100:1101,length = 40),

barplot(2?) with CI from a zero reference line
Dear R Users, (and dear Marc) First of all many thanks for the answers to my previous questions. I would like to barplot the mean percent change of a variate with it's CI. Bars should start from the zero reference line to height (in barplot2). Is there a way to tweak barplot2, for example, to do that ? I have tried to see what the function was but unlike other functions was not able to

Using format to add leading zeroes
I have a numerical vector which contains a (poorly) formatted time column, which, in theory, should be HHMM, but was distributed as an integer, so, for 12:15 am, it is saved as "15" (e.g. HHMM = 0015 with the zeroes stripped). I'm trying to use this in conjunction with strptime, but I'm thinking because each time is an integer ranging from 1 to 4 digits, I probably need to

R issue with unequal large data frames with multiple columns
I'm a bit of an amateur R programmer. I can do simple R scenarios but my handle on complex grammatical issues isn't steady. I have 12 CSV files that I've read into dataframes. Each has 8 columns and over 2000000 rows. Each dataframe has data associated by time component and a date component in the format of: X.DATE and then X.TIME X.DATE is in the format of MMDDYYYY and X.TIME is

subset and as.POSIXct / as.POSIXlt oddness
Dear R users, Given this data: x <- seq(1,100,1) dx <- as.POSIXct(x*900, origin="2007-06-01 00:00:00") dfx <- data.frame(dx) Now to play around for example: subset(dfx, dx > as.POSIXct("2007-06-01 16:00:00")) Ok. Now for some reason I want to extract the datapoints between hours 10:00:00 and 14:00:00, so I thought well: subset(dfx, dx >

Error with strptime
Dear All, I am trying to convert to POSIXct after pasting a date and a time in character format with strptime. It is probably obvious but I don't understand why I get an error message after bsamp$spltime<-strptime(test,format="%d-%B-%y %H:%M") whereas I can get what I want if I do it in 2 steps and rbinding ?

Timezone and date
When I do the date +%Z I get the timezone. Which currently is EDT. I am sending information to another system, that says EDT is not a valid timezone. I have no way to modify the other system. My question is - is there a way to get the non-day-lite savings time zone ? For example EST is valid - EDT is not. Just curious if there is an easy way already present to get a standard time zone. Thanks,

reformat time from hhmm
Hi, I'm newish to R, a recent convert from Matlab... So far I'm impressed, and determined to solve the following problem, which seems like it should be easy: I have a long (millions of points) data series recorded with a datalogger that produced a timestamp in 4 columns: Year, Day of Year, Time in (H)HMM and Seconds. I would like to have R interpret these columns as a time object and have
