Hi everyone! I have some problems concerning missing values in time-series data. I have 11 values for each subject, with values being hormone dosage at different time points (0, +40, +50, +55...). Some of these values are missing. I want to impute data and I have to use univariate, non equi-spaced, time-series imputation methods. I tried the "zoo" package, with na.approx() and na.spline() functions. The na.approx() replaces NA by linear interpolation while na.spline() replaces NA by cubic...

Hi We counted the number of ants on two different feeders every 5min over 60min. I would want to show with my graph the amount of ants on a feeder over the whole time + separated into the two feedertypyes. So two bars per timepoint. Usually I always use the following base code for ggplot: p1 <- <- ggplot (data, aes(x = time_after_start, y = AntsOnFeeder))+ scale_y_continuous(expand = c(0, 0)) + geom_point( alpha = 0) + stat_summary(fun.y = "mean", geom = "bar", fill="dodgerblue4") +... ggplot2 how to display meanbars instead of maximum bar-numbers ..read more

My office closed and we now work from home. I connect through a VPN (it is a state computer and there are serious concerns with security). My internet connection, which used to be the state one now turned off, is in practice 60 megs down (in theory 100 but it never is) and 5 up. Things are a bit slower then before, but not much except with R which is incredibly slow now. Any suggestion - I am assuming the VPN does not play nice with R. I am hoping there is some way to fix this. Or make it... Trouble connecting to R ..read more
