I have just started using RStudio and would appreciate some help.
I am considering an experiment where a group of people were asked to solve a soduko puzzle. The time they spent on solving the puzzle was noted.
I have loaded the data in RStudio and defined new variables to the dataset such as Time and the log of Time. But when I try to find the mean, variance and standard deviation an error appears.
Here is my code (Tid stand for time):
ssData <- read.table("ss1920-udenhold.txt", header=TRUE) ssData <- transform(ssData, Tid=60*(ssData$Min) + ssData$Sek) ssData <- subset(ssData, Tid>0) latinData <- subset(ssData, Type=="Latinsk") ssData <- transform(ssData, logTid=log(Tid)) mean(Tid) mean(LogTid)
Appreciate the help.
