So far I've done this:

tableau

snipped data

attach (tableau)
tableau <- lm (AchE ~ Temps.s. * Modalite, random = ~ 1 | individu)
Erreur dans storage.mode(y) <- "double" : la modification du mode de stockage
Even without an English translation, it seems very likely that the AchE variable is not of numeric class, but rather a factor. You may want to redo your data input step with a setting for the decimal separator set properly for the conventions of your locale settings. See help(read.table)
And the other _big_ problem that I did not notice at first is that
you are overwriting your data with the model output. This isn't
exactly the problem addressed by fortune("dog") but an even more
severe case of identity conflation. This is even a further example of
why it is a bad idea to use the attach function.
You may also want to look at the settings for locale if you will typically be using "," as a decimal separator. ?options ?locales
