After checking the original data in Excel for blanks and running Summary(cm3) to identify any null values in my data, I'm unable to identify an instances. Yet when I attempted to use the data in Random Forest, I get the following error. Is there something that Random Forest is reading as null which is not actually null? Is there a better way to check for this? > lib...

Dear R users, I have the following two problems, related to the function sub, grep, regexpr and similia. The header of the file(s) I have to import is like this. c("y (m)", "BD (g/cm3)", "PR (Mpa)", "Ks (m/s)", "SP g./g.", "P (m3/m3)", "theta1 (g/g)", "theta2 (g/g)", "AWC (g/g)") To get rid of spaces and symbols in the names of the columns, I use read.table(... check.names=TRUE) and I get: str <- c(&...

...rather than do this 240 times, I would like to tell R to repeat the process automatically using loops or any method that works.   Code:   RG2<-BCI[BCI$Species == "APEIME" & BCI$Individual == 1 & BCI$Core == "a", ] > plot(x=RG2$DP..cm., y=RG2$WD..g.cm3, xlab="Distance from pith cm", main="APEIME1a", ylab="Wood density g/cm3") > RG2lm<-lm(RG2$WD..g.cm3~RG2$DP..cm.) > summary(RG2lm)   Thanks   Oyomoare [[alternative HTML version deleted]]

Dear Rexperts, I am trying to add a '+' identifying the mean in a boxplot using the following sizelist <- split(size, grp) centers <- boxplot(sizelist, style.bxp = "att", medpch = "o", ylab = "Prostate Volume (cm3)") points(centers, unlist(lapply(sizelist, mean)), pch = "+") But, I get error Error in xy.coords(x, y) : 'x' and 'y' lengths differ which I do not understand. The data follows grp size AE 9.132 AE 10.07 AE 20.077 AE 14.691...

Some of you may remember back in May the thread on using Asterisk as a voicemail server for a Cisco Callmanager system. My own Callmanager system is integrated into an Asterisk server for voicemail (and other things). Back in May I was using H323 for integration, but since I've upgraded to CCM 4.1 I have switched over to SIP. The integration with H323 required using Call forwarding to send
