I want to especially know mean, median, maximum etc. Thanks. Janesh [[alternative HTML version deleted]]

...ny suggestion then I could try on ggplot. I know how to create basic plot with 3 series in ggplot but don't know how to use facet and then use 3 series in each sub plot. As I am a new user in R and ggplot and on a learning curve please excuse me if this question is very naive. Best Regards, Janesh Devkota [[alternative HTML version deleted]]

...ing I need to do is create another sub data set where both the series have common data. One data might have more intervals than another. After I find two data sets of same interval then I want to plot a correlation graph. I hope I made it clear what I want to do. Thank you so much.

Hi I am trying to find the relationship between two variables. First I fitted a linear model between two variables and I found the following results: Residual standard error: 0.03253 on 2498 degrees of freedom Multiple R-squared: 0.5551, Adjusted R-squared: 0.5549 F-statistic: 3116 on 1 and 2498 DF, p-value: < 2.2e-16 Then I used the cor function to see the correlation between two variable

...our data mydata <- read.csv("mydata.csv") head(mydata ) summary(mydata) #Create a contourplot contourplot(Salinity ~ Eastings+Northings | Time, mydata, cuts=30,pretty=TRUE) Thank you so much. I would welcome any other ways to do this aside from contourplot and lattice. Best Regards, Janesh [[alternative HTML version deleted]]

...those data on different columns will be combined in 1 column of data. So, I want to arrange the data columns such that first the data on row 1 will be used and then data on second row and so on. This way, we will have one column for one time. Thank you for your help and suggestion. Best, Janesh [[alternative HTML version deleted]]

Hello All, I am trying to do the time series analysis in R and I want to assign a vector as a time series. The data I provided is hourly. The data is from Jan 1 2008 to Dec 31 2009. How can I assign the data such that the first year is leap year and second is not ? airtemp <- read.csv("airtemp.csv",header=T,sep="") aw <- ts(airtemp,start=2008,frequency=8784,end=2009)

I am trying to solve an integral in R. However, I am getting an error when I am trying to solve for that integral. The equation that I am trying to solve is as follows: $$ C_m = \frac{{abs{x}}e^{2x}}{\pi^{1/2}}\int_0^t t^{-3/2}e^{-x^2/t-t}dt $$ [image: enter image description here] The code that I am using is as follows: a <- seq(from=-10, by=0.5,length=100) ## Create a function to compute

...)),each=6239)) p <- ggplot(data=watersurf,aes(x=time,y=data,group=id))+geom_line(aes(linetype=group1),size=1)+facet_wrap(~coupleid) p Is it also possible to add third series in the graph but of unequal length i.e not same interval ? Thanks. Best Regards, Janesh Devkota [[alternative HTML version deleted]]

I have a time series of more than 2500 points. I also have observed data set but it is not continuous. I want to use the observed data set and find out the modeled data from the time series data. After the modeled data has been found out for the same time I want to plot the correlation plot and display the equation and coefficient of correlation on the plot. The sample time series can be found on
