Hi, I have the following dataframe. The County Column has many empty spaces at the end. I want to cut out the empty space and put them back into the dataframe.

Hi, I plotted 12 graphs on a page and output to a png file. I wanted to have an overall title for all 12 graphs. What command can I use to do this? Below is the code that plotted the 12 graphs in one page. # FM10 by Month/ Export the plot to Wash2005FM10.png png(file="Wash2005FM10.png",bg="white") par(mfrow = c(3,4)) # Plot 12 Month of OFM10, FFM10 for(i in

Hi, I have a dataframe Wash2005, which has daily weather data. I am doing a regression by month as follows: # FM10 Regression by Month # Plot 12 Month of OFM10, FFM10 for(i in 1:12) { Temp <- subset (Wash2005, MM == i) assign( paste('Wash2005FM10', strtrim(month.name[i],3), sep=""),lm(Temp$FM10.1 ~ Temp$FM10)) } Wash2005FM10Jan, Wash2005FM10Feb, etc holds the

Hi Eric, the following works for me. HTH, Eric library(EGRET) StartDate <- "1990-10-01" EndDate <- "2017-09-30" siteNumber <- "10310000" QParameterCd <- "00060" Daily <- readNWISDaily(siteNumber, QParameterCd, StartDate, EndDate) # Define 'center of mass' function com <- function(x) { match(TRUE, cumsum(x/sum(x)) > 0.5) -

Hi, I am playing with clogit(case~spontaneous+induced+strata(stratum),data=infert) from clogit help file. This line works. 1. But, why strata(stratum) doesn't have a coefficient like spontaneous and induced? 2. When I remove strata(stratum) from the command, this function seems to keep running forever. Why? 3. I think the equation for clogit looks like P=1/(1+

Hi, I have Forecast Class and Observed Class in a data matrix as below. > Sample1 FCT OBS 1 1 5 2 2 4 3 3- 3+ 4 3 3 5 3+ 3- 6 4 2 7 5 1 I want to find the difference between Observed and Forecast Classes. How can I get this done? I tried to following to convert the 1 through 5 classes, to 1 through 7 for both OBS and FCT column. > Sample1$OBS2 <- Sample1$OBS

Hi, I render a couple of date_select fields, the HTML looks fine, I can see the values submitted back to the server, but AR doesn''t pick them up from the hash in Booking.new(params[''booking'']). I''ve got a ''booking'' object with parameters product, startdate and enddate. HTML snippets: <select

I must be stupid because this cannot be this hard. I''m trying to build an all day calendar event. In most clients it shows up as an entry at the top of the day rather than blocking out the whole day with an event. I have a bit of code that looks like this... cal.event do dtstart DateTime.parse("#{startDate.year()}-#{startDate.month()}-#{startDate.day()}") dtend

Hi, I would like to make @dates in my controller. I tried the following: startdate = Time.now enddate = startdate.next_week for enddate > startdate @dates << startdate startdate = startdate.tomorrow end But I get an errormessage when I check the syntax: "warning: useless use of a variable in void context" Anyone? Thanks! Steven. -- Posted via

Hi R, How to get the range of values form startDate to lastDate as given below?. #***************************************************************** # Load historical data #****************************************************************** library('quantmod') endDate =Sys.Date() startDate = as.Date(endDate-30, order="ymd") dataspy = getSymbols("SPY", from = startDate,

Eric B's response provided just the kind of quick & simple solution I was hoping for (appears as the function com below). However, I once again failed to take advantage of the power of R and have reverted back to using a for loop for the next step of the processing. The example below (which requires the library EGRET for pulling an example dataset) works, but probably can be replaced

in my booking / _form I have the following input fields : (startdate and endate) <div> <label for="startdate">Booking Start Date</label><br /> <%= text_field_tag(''startdate'', @startdate, {:class => @startdateclass, :readonly => "readonly", :maxlength => "25"} ) %> <%= observe_field("startdate",

I am having trouble with creating a POSIXct object. If I create a variable of class Date first out of the date part of my data, I am ok, but if I just paste the date and time parts together and try and create the POSIXct object, I have problems. Here is a toy example created from the actual data which caused the problem. I am using R 2.0.1 on Windows XP. > # Data frame with dates and

I am using the date_select helper to generate date select elements in a form. I notice that the generated HTML shows that these selects have the following names: Month: current_job[StartDate(2i)] Day: current_job[StartDate(3i)] Year: current_job[StartDate(1i)] I''m assuming that the Xi identifiers somehow specify the appropriate date part from a date or time value. Can anyone

Hi All, I am iterating through dated materials, with variable start and end dates, and would like to skip procedures everytime I encounter a weekend or holiday. To do this, I thought the easiest way would be to create a TRUE/FALSE vector corresponding to each day where it is TRUE if a workday, and FALSE if a weekend or holiday. So far I have been able to do this for weekdays: startDate <-

Hello, fellow R enthusiasts. Ok, I've been racking my brain about this small issue, and between searching the help archives and reading through the plot-related documentation, I can't figure out how to achieve my desired endpoint without some ugly, brute force coding. What I would like to do is make a plot in which only a subset of my data are plotted, but in regular intervals, such as

Hello - This is not a real problem, just an annoyance. Sometimes, but not always, I get a set of strange warnings from hist(). Example follows. ############################ #Produce a histogram of start dates for a set of field measurements. # I didn't reproduce all the dates, because not sure it's relevant, but here's a sample. # Note the invalid date in the fifth element. >
