You need to make sure that the rJava package is working. Consider using the readxl package instead of xlsx. Best regards, ir.

Dear All, 1.I have been trying to aggregate my data but I have not been getting it correctly. In the data I want to convert hourly data into daily averages. Here is a sample of the data: Neph_no Date Time Temp_C Pressure_kPa RH 9 2014/03/28 10:00:00 38.4 95.9 29.7 9 2014/03/28 11:00:00 37.8 95.8 29.2 9 2014/03/28 12:00:00 36.7 95.8 35.1 9 2014/03/28 13:00:00 35.4 95.8 38.9 9

Hi, the command line with 'text' should be: text(-8,-8, expression(R^2 * " = 0.62, r = 0.79, N = 161"), cex = 2 ) Best, Kimmo su, 2024-02-04 kello 17:16 +0100, Jibrin Alhassan kirjoitti: > Here is the script I used to plot the graph indicating the text I > wanted to > insert.

Hi Elo, It gave this error message: CR_plot2.R:14:37: unexpected string constant 13: plot(FDapt,FDcli, pch = 16, cex.lab = 1.6, cex.axis = 1.4, cex.main = 0.8, font.lab = 1.7, font.axis = 1.7, col = "red",main = "Simultaneous Events at CLMX and APTY",ylab="CLMX",xlab="APTY") 14: text(-8,-8, "expression(R^2*"= 0.62"), r = 0.79, N =

Here is the script I used to plot the graph indicating the text I wanted to insert. The line in the script that I have issues with is: text(-8,-8, "R^2= 0.62", r = 0.79, N = 161", cex = 2 R^2= 0.62 is not producing R squared = 0.62. Thanks. Sys.setenv( TZ="GMT" ) dt <- read.table("CLMXAPTY_sim", col.names = c("FDcli", "FDapt"))

Thank you Zhao for the code. When I replotted the graph after inserting the code in my script, it gave me this error message without plotting the graph: Warning message: In lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : extra argument ?col? will be disregarded.

I have done a scatter plot in R. I want to insert the coefficient of determination R^2 = 0.62 as a text in the plot. I have tried to write R^2 but could not produce R2. I would appreciate it if someone could help me with the syntax. I have tried: expression(paste("", R^2,"=", 0.62)), but it did not produce R squared, rather it gave me error messages. Thanks. Jibrin Alhassan

I installed opensuse 12.2, and upgraded the samba 3 it came with to samba 4.

Does samba 4 really support win 8 prof or we have to wait for some time? Emeka
