get.datetime error

[shburnet]

I'm currently working on a headmap from my thermistor string data and am receiving errors for the following code:

depths = get.offsets(wtr.all[,2:nn]) Warning message: In drop.datetime(data) : Unable to find a datetime column. Assuming no datetime column was supplied.

Further code shows:

wtr.dates = get.datetime(wtr.all, error=TRUE) Error in get.datetime(wtr.all, error = TRUE) : could not find function "get.datetime"

My code prior to that works without error so I'm not sure what may be the issue since I can see datetime data is loaded.

Thanks in advance.

can you add to this issue what

head(wtr.all)

looks like?

[shburnet]

head(wtr.all) datetime wc_1 wc_3 wc_5 wc_6 wc_7 wc_8 wc_9 wc_10 wc_11 wc_13 1 2017-05-31 00:00:00 12.40 12.59 12.30 12.69 12.59 12.30 12.11 12.30 12.11 12.50 2 2017-05-31 01:00:00 11.24 11.43 11.14 11.53 11.24 11.04 10.65 10.85 10.65 11.33 3 2017-05-31 02:00:00 10.06 10.36 10.06 10.36 10.16 9.87 9.57 9.77 9.47 10.16 4 2017-05-31 03:00:00 9.47 9.77 9.47 9.77 9.57 9.37 8.88 9.18 8.88 9.57 5 2017-05-31 04:00:00 9.47 9.57 9.47 9.57 9.37 9.37 9.47 9.37 9.47 9.47 6 2017-05-31 05:00:00 11.33 11.33 11.24 11.53 11.53 11.53 11.53 11.53 11.43 11.53 wc_16 wc_19 thermo.depth top bottom 1 12.40 12.88 NaN NaN NaN 2 11.14 11.63 NaN NaN NaN 3 9.97 10.55 7.959233 7.959233 7.959233 4 9.47 9.87 NaN NaN NaN 5 9.37 9.67 NaN NaN NaN 6 11.43 11.72 NaN NaN NaN

Can you post the function call you are using to make the heatmap?

are you using

wtr.plot.temp(wtr.all[,1:nn])

?

Note from the examples you'll not want to exclude the datetime column, which is what I think you are doing when you use the "2" in wtr.all[, 2:nn]

[shburnet]

I'm not using wtr.plot.temp as you mentioned above but I'll work on that next.

Instead I was using the code from wtr.heatmap.layers.R page which I was able to get a temperature plot from.

[jordansread]

Ok - are you no longer having an issue then?

[shburnet]

Sorry, still having the issue when running the heatmap code.

with wtr.all as you requested earlier I have:

head(wtr.all) datetime ms_1 ms_3 ms_5 ms_6 ms_7 ms_8 ms_9 ms_10 ms_11 ms_13 1 2017-05-31 00:00:00 12.30 12.88 12.69 13.08 12.40 12.79 12.59 12.50 12.21 12.30 2 2017-05-31 01:00:00 11.14 11.72 11.43 11.72 11.14 11.63 11.33 11.24 10.94 11.14 3 2017-05-31 02:00:00 10.06 10.55 10.36 10.75 10.16 10.55 10.26 10.06 9.87 10.06 4 2017-05-31 03:00:00 9.57 9.97 9.77 10.06 9.57 9.97 9.77 9.57 9.37 9.47 5 2017-05-31 04:00:00 9.37 9.57 9.47 9.67 9.47 9.57 9.47 9.47 9.37 9.28 6 2017-05-31 05:00:00 11.53 11.63 11.72 11.72 11.63 11.72 11.72 11.72 11.63 11.53 ms_16 ms_19 ms_23 thermo.depth top bottom 1 12.11 12.88 12.30 NaN NaN NaN 2 10.85 11.72 11.14 NaN NaN NaN 3 9.87 10.65 9.97 NaN NaN NaN 4 9.28 10.06 9.37 NaN NaN NaN 5 9.28 9.57 9.47 NaN NaN NaN 6 11.53 11.82 11.72 NaN NaN NaN

When I reach: wtr.dates = get.datetime(wtr, error=TRUE) # turn datetime into vector

I have an error as I mentioned earlier: Error in get.datetime(wtr, error = TRUE) : could not find function "get.datetime"

And with: wtr.plot.temp(wtr.all[,1:nn])

[jordansread]

@shburnet please paste in the function call you are using, e.g.,

library(rLakeAnalyzer)
wtr <- load.ts('my_temperatures.csv')
wtr.heatmap.layers(wtr)

I don't know what this code is that you are using, so it is hard to help:

Instead I was using the code from wtr.heatmap.layers.R

You can get help on the get.datetime() function with

?rLakeAnalyzer::get.datetime
